with no link for the given listbox(es), so just verify the value
of the text in it.

-  [hal_json] distinguishes between REQUEST.form and REQUEST.other
-  [hal_json] byteify all keys and values before putting them into REQUEST
-  [renderjs_ui] dialog does not go to parent when validation fails
-  [hal_json] does not crash on direct traverse of a Script instead of a Dialog
-  [renderjs_ui_test] move the logging-out test to its isolated zuite so it does not cause problems

-  introspect any dialog method for `uids` argument
-  introspect any list_method inside dialog for `uid` argument
-  module-level Object JIO Actions are templated and they expect `query` parameter
-  use `form_id` to obtain previous search result
-  warn user when applying an action on unrestricted set of documents

This fixes the problem that deferred style does not honor Localizer cookie and just translate according to user agent's `Accept-Language` [#20180319-1D1E0A3](https://nexedi.erp5.net/bug_module/20180319-1D1E0A3/) 

Filtering of request arguments have been reworked to stop code duplication and fix [#20180220-1DBF516](https://nexedi.erp5.net/bug_module/20180220-1DBF516)

In legacy simulation, we use to have a matrix of predicate containing *Accounting Rule Cell*, with some (probably) buggy interactions to maintain the matrix of predicates.

When moving to new simulation we realized we can just do this configuration using trade model path, so this is no longer needed.

The configuration *Rules contain Accounting Rule Cells* was already moved to `erp5_simulation_legacy`.


There are two other parts of configuration that were also used only used with Accounting Rule Cells in rules::

 * *Rules and Predicate use an interaction workflow to update matrix* - and the corresponding (missnamed) `rule_interaction_workflow`
 * *Rules contain Predicate*

This MR just move these two bits of configuration to legacy business template.
