[IMP] mass_mailing_list_dynamic: make user aware of list change

- Adds is_synced field to track whether a dynamic list has unsynced
changes or not so the user is aware that the definitive number of
contacts is yet to be determined.
- It fixes an issue that made impossible deleting a res.partner filter
when a list had use it to filter contacts.
- It also shows only the filters available for the user (shared and
belonging to self).
