[FIX] web: send correct filter's context when saving filter

Before this commit, the context coming from the action was
merged with the context of the search items to generate the
context of the filter to save, when the user clicked on "Save
current search", whereas it should not.

There is an ActionService test attesting it, but it currently
uses a ListView, which is still legacy, so the new faulty code
wasn't tested.

closes odoo/odoo#81049
