[FIX] microsoft_calendar: allow resetting account with option deletion

Before this commit, when the microsoft sync was reset with the following options:
- Delete from the current Microsoft Calendar account
- Delete from both

An rpc error was encountered:

requests.exceptions.HTTPError: 400 Client Error: Bad Request for url:
https://graph.microsoft.com/v1.0/me/calendar/events/<event_id>

After this commit, the local events are deleted if necessary and
the non-recurring events are deleted on microsoft. We keep the
recurring one to be consistant with
