[FIX] web client fix: crash when loading translation

Problem happens when the user from the website tries to load a translation,
it opens up a modal window without an action.  But the modal has a (hidden)
searchview which tries to load custom filters corresponding to that
non-existing action.

Another problem at the same time was that the view manager could not
display the breadcrumbs for a non-existing breadcrumb.
[FIX] update tests and change search logic (webclient)

previous commit broke some tests.  The issue is that the search view
now avoid making requests if there is no action id.  But this is an
assumption that tests use, so some slight adjustments have to be made.

Also, this is the moment to give properly the action id to the favorite
menu.  Instead of bypassing its parent, it now receives the action id
from the search view.

process.

[FIX] fix debug mode: correct id and xml_id (web client)

This commit fixes two issues with debug mode:

initialized without its view_id. Problem is that it prevents debug mode from editing the view.
*  add xml_id in Edit action form view(debug mode) : this makes the xml id visible in form view
