BUG-8445: check sessionId before propagating failures

When we have leader movement ocurring, based on timing details we
can re-establish a connection to the new leader and then start
receiving responses from the old leader telling us it no longer
is the leader.

To stop this from happening we need to check connection session ID
against the incoming failure.
