[$80] Delete/Re-connect Calendar Integration

maxceem commented 2 years ago

Once user connects calendar its shown here

At the moment there issue, it shows undefined, but it has to show the email address which has been used to connect calendar.

We have to always show the email of the calendar which user connected on this screen instead of undefined.
But at the moment we don't store connected calendar email in TaaS API so we have to start storing it
After that we have to make sure that removing calendar and/or re-connecting works good from good end-to-end:
- we should be able to remove connected calendar by clicking remove button (it was already implemented using mock API, there might be small integration issues to fix)
- if calendar is already connected, we should be able to connect another calendar and it would replace previously connected one (I guess this should already work, just verify and fix if anything)

Update UserMeetingSettings model, so it also stores email for each connected calendars of the user. So objects inside UserMeetingSettings.nylasCalendars should have email field.
When we connect calendar we should save email inside UserMeetingSettings.nylasCalendars[*].email when saving or updating calendar
Also, when user first time creates interview and doesn't have UserMeetingSettings, then we create UserMeetingSettings and Nylas Virtual Calendar, see code https://github.com/topcoder-platform/taas-apis/blob/feature/interview-update/src/services/InterviewService.js#L310-L319. In this case we have to also save user email. I guess the best is to update method which creates Virtual Calendar so it returns calendar object with email, here https://github.com/topcoder-platform/taas-apis/blob/feature/interview-update/src/services/NylasService.js#L35-L58
Note, we can get email of account when calling getAccessToken
