This allows code of movement group to still works when they use
setter/getters defined by property sheets

Fully rewrite portal_simulation.mergeDeliveryList to use builders to reconstruct new
merged delivery.

Add parameter "merge_delivery" to builder. This parameter is used when
merge should be done in such a way that movement group at delivery
level are ignored

For example, testReceiptRecoginition employs numpy matrix calculation methods
that try to utilize all the CPU in the computer. This behavior is harmlfull
when there are several testReciptRecongnition is running in a testnode which
has 40 CPUs.

To get the listbox cell value : code was getting last proxy target
instead of browsing the full proxy target stack.

- the "Equal to (at least one)" operator is displayed in the same listbox as "Equal to" and "Contains" ;
- this filter item can have multiple input value field ;
- one input value field has to be filled (required) like on the other filter items ;
- when extended_search is `title: ( "One" OR "Two" )`, behavior changed :

Activate copy/paste/delete buttons on form list and form view.

When selection listbox lines, only use what is visible / checked.
This is required because of list methods which do not support catalog queries.

This changes the behaviour of mass workflow transition action and delete action,
but at least, it is consistent everywhere now, and so, easier to explain (what you see is what you change).

The listboxes in mass delete / state change dialogs are only used to confirm the lines selection.

Introduce a new ERP5Site_resetAccountingTransactionLineGroupingReference
script to reset grouping reference on accounting transaction lines.

This solve a problem with the way we activated on
AccountingTransactionLine_resetGroupingReference the context of the
line, if line was removed from OFS before activity was executed, the
activity was discarded and grouping references on related lines was not
reset.

Also drop the unused `keep_if_valid_group` parameter, it was not making
sense.

Also, make some existing sanitation happen earlier than before, to store
values in a cleaner format.

default is to run all tests

When there was parallel execution of this alarm with lots of non grouped lines, it can happen that lines are grouped but not indexed yet.

With recent changes in CMFActivity, getServerAddress is now used
when setting up the site, before the ZServer is started, which means:
- getServerAddress memoized a wrong return value;
- the test didn't fail with --load.
