[FIX] microsoft_calendar: delete events correctly when reseting account

Before this commit, if you reset your microsoft callendar account and
set to remove events from Odoo, it won't remove them. The problem is
that the ('ms_universal_event_id', '!=', False) condition is not
implemented, and it can't remove the existing events.
