Only enqueue tasks when transaction is successfully finished.
When a transaction conflicts, the ISavepointDataManager's commit() method is called, followed by tpc_abort().
When the transaction is successful, commit() is called followed by tpc_finish().
Since we cannot roll back putting something in the queue we must enqueue the task in tpc_finish() and not in commit().
We assume that enqueueing a task does not fail.
