[calendar/messaging] fix connected account auth failed should skip sync (#4920)

- AuthFailedAt is set when a refreshToken is not valid and an
accessToken can't be generated, meaning it will need a manual action
from the user to provide a new refresh token.
- Calendar/messaging jobs should not be executed if authFailedAt is not
null.
