Fix backfill of _sync_id

If we receive an exception to a recurring event before we receive
the event, we back-fill the originalSyncId when the event finally
arrives.  The sql command that did this wasn't specifying the
calendar, which caused problems when different calendars had
(unrelated) events with identical _sync_ids.
