Won't sync events from Google: "Backend factory for source (...) and extension 'Calendar' cannot be found"

### What Happened?

Calendar fails to synchronize events.


This is similar to #734

### Steps to Reproduce

1. Go to Online Accounts, add new IMAP account. Mine is a Google account.
2. Open Calendar. See error message in a red banner.

### Expected Behavior

Mail app works (shows my email), but Calendar doesn't show any events.

EDIT: If I add the account from Evolution (OAuth2), the calendar works as expected.
