Create Virtual Calendar if we have UserMeetingSettings with all deleted calendars

[maxceem]

If we connect Google/Microsoft calendar using the same email as logged-in user email and then remove it the meeting would be created anyway using some calendar.

1. Use user who doesn't have yet UserMeetingSettings record

2. Connect Google or Microsoft calendar using the same email as logged-in user email

3. Remove connected calendar. So the UserMeetingSettings for the user would look like:

   

4. Now try to schedule a new meeting. It would be scheduled using nylasCalendarId which is not listed in UserMeetingSettings.

Expected behaviour:

• As there is no not-delete calendar, we have to create a new Virtual Calendar
• Save that Virtual Calendar into already existent UserMeetingSettings record
• Create new meeting using this Virtual Calendar
• NOTE: if Virtual Calendar already exists in Nylas, then on this line https://github.com/topcoder-platform/taas-apis/blob/dev/src/services/NylasService.js#L43 we have to make sure that we use from Nylas Virtual Calendar and we don't use one of the Google/Microsoft calendar with the same email. So I guess we should not use getPrimaryCalendar here, and we have to update the logic createVirtualCalendarForUser method:
  • we have to get existent calendars
  • try to find if there is existent virtual calendar (not google or microsoft)
  • if have some virtual calendar, then use it
  • if don't have virtual calendar, then create it

QA note: it's hard to test it without checking code and DB state, so we would not pass it to QA.

Closing, as it cannot be tested by QA.
