Simon Charette d35ce682e3 Fixed #33506 -- Made QuerySet.bulk_update() perform atomic writes against write database.
The lack of _for_write = True assignment in bulk_update prior to
accessing self.db resulted in the db_for_read database being used to
wrap batched UPDATEs in a transaction.

Also tweaked the batch queryset creation to also ensure they are
executed against the same database as the opened transaction under all
circumstances.
