This property is only conditionally set, which causes distracting error
when something goes wrong. If we really want to check that the expected
code path was followed there has to be a better check and a more debugging-
friendly error than an AttributeError.

While it does not make sense, it is possible to spawn activities with a
group_id set but without a grouping_metohd_id. This is for example easy to
trigger using recurseCallMethod from ERP5Type.Core.Folder: the
_recurseCallMethod activity spawned nullifies grouping_method_id but does
not (currently) clean group_id, leading to inconsistency between how
"non-groupped" conditions are evaluated in getProcessableMessageList and
dequeueMessage.
The consequence is zombie activities: they never fail, do not prevent other
activities from being executed, but and are permanently run on the node
which reserved more than one because:
- all but one activity is in MESSAGE_NOT_EXECUTED state, forcing an abort
- finalizeMessageExecution does not understand that MESSAGE_NOT_EXECUTED
  activities may not have failed, and itself fail while trying to detect
  the failure type (ConflictError vs. others), failing to free & postpone
  the activity, in turn failing to bring it to eventually permanent failure
  state.
Make those conditions consistent, and use tuple-unpacking to detect any
future inconsistency much earlier, simplifying debugging.

group_method_id column is declared "NOT NULL", so it can only be None if
getProcessableMessageList could not find any activity, in which case this
code is not executed ("if message_list" is false).
This simplifies two "if" statements.

Unsure whether this makes a difference, but let's be on the safe side.

Base domain .getRelativeUrl method does not include portal_domains.

Clone Base_doAction to keep the logic identical.

Reuse Folder_create directly to reduce difference from xhtml_style.
Side effect: the status message is modified from 'Document created.' to
'Object created.'

This works only for medusa, using the same approach as CMFCore's

Also increase test coverage of google/facebook plugins.

What I'm trying to prevent, is that when we have a document with leading/trailing space

![image](/uploads/8a00a1019cdcb5d76bd589917548a515/image.png)

and it's set in a relation
![image](/uploads/925aa9895c7d15f3ef9f3bdc9926d7fd/image.png)

just clicking save will complain that document is not found

![image](/uploads/a559eea23fc8ba0df19c23dfcda26138/image.png)

this is because validator have stripped whitespace and search for `"leading and trailing space"` - and find nothing  (unless title is a keyword key, but that's another story )

Until know, in the preference we defined list of uri for conversion
server, and then we were trying always in the order defined in the
preference. But this is not optimal, when a server start to fail, it's
better to try using another one. So sort list of uri in such a way to
use first server having the most chance to work.

Useful for SolverType._configuration_property_dict but more generally
the whole history should be displayed as this view is used by developers.

erp5_web_renderjs_ui: Don't crash if form has 'Update Action Title' but no 'Form update action' defined.

Even though this is inconsistent form definition, form_dialog gadget should not crash

in MRP, we have manufacturing execution having a mix of lines with
positive and negative values. It must be possible to use split and
defer solver in that case.

For example, Categories in "expired" state.

As a consequence, user is included in cache key.

This function have evolved to something very trivial not accessing anything from database, so caching this no longer really makes sense, also the cache keys are really big.

On a quick benchmark of calling ERP5Site_getTabList 10000 times:
with cache: ERP5Site_getTabList took 12.961781
without cache: ERP5Site_getTabList took 5.395873

Only send line data if the text is not empty and ensure there is no hole
in the uid list.
This will fix the edition when the field already contains some homonyms.

Only append empty input if the latest one is not empty.

Replace verify by assert in the tests.

When we ignore variations, we should also ignore them when looking

Add some tests and fix bugs:
* https://nexedi.erp5.net/bug_module/20170426-A3962E
* another bug that columns names were not escaped ( in a project we have a custom table with a column named `use` and this breaks `upgradeSchema`  )

Note that we can't really use " " in test tables, for input selenium
supports ${space} magic that types a space characters, but to check the
values, we cannot just use assertValue which strips the leading/trailing
spaces, so we use a custom assertEval expression.
