REVISION SUMMARY
  According to https://developers.google.com/calendar/v3/errors, the server can return a 410 error if the syncToken or updatedMin is too old.
  There is already code to preemptively request a full sync, but specifically for the "Contacts" calendar the server-side limit is much lower than usual, generating these errors and preventing sync.

TEST PLAN
  - Set last sync for "Contacts" calendar to five days ago.
  - Observe 410 error being returned.
  - Verify that a full sync is performed.
