Naturally, the listen should not do anything at all when followed by a
rollback.
However if you start listening in a transaction then you should get all
events that have happened after the snapshot that the transaction
represents (the start of the transaction).
That means that events that happen after the start of the transaction
have to be returned in the next transaction.
