Relax assertion on transaction rollback failure (#2052) 

In case a failure happens when a transaction is rollbacked,
we used to hit an assertion for ensuring there is no pending
activity on the connection. However, that's not true after the
changes in #2031. Thus, we've replaced the assertion with a more
generic function call to consume any pending activity, if exists.
