Only cancel Meeting room booking when the room is auto-canceled

When check-in is required and not made within the check-in window: 

• Delete the meeting from the meeting rooms calendar 

• Keep the meeting in all employees' calendars (organizers and guests)

• When a meeting is canceled from the OfficeRnD interface (WP, mobile, AP), still cancel the entire meeting for all attendees + the meeting room.

• If multiple rooms are added to one meeting, remove only the one which is auto-canceled 

• Cancel instead of deleting bookings on Outlook deletion events to save them for reporting purposes.
