If a transaction has been started by an async query, and the transaction is closed
before the async query has returned the first results and the transaction ID, the
transaction would not be rolled back by the client. This would cause locks to be held
for longer than they should.

This fix adds a check whether the transaction has already sent a request that will
start the transaction, and if so, it will add a callback that will rollback the
transaction when the transaction ID is returned.
