Switch to using the action_id itself instead of reverse-matching action_id from view_id
* Not all ir_act_window have a view_id, for some we're supposed to go through ir_act_window_view
* Multiple ir_act_window (or ir_act_window_view) may have the same view_id, and we don't really have enough information to select the right one
Keep the old resolution via view_id for now, in case users update their web client and their addons out of sync
