Previously, when a session was reattached, all the close/failure listeners
were removed from the old connection and set onto the new connection.
This only worked when at most 1 session of the old connection was
transferred: When the second session was transferred, the old
connection already didn't contain any close/failure listeners anymore,
and therefore the list of close/failure listeners was overwritten by
an empty list for the new connection.
Now, when a session is being transferred, it only transfers the
close/failure listeners that belong to it, which are the session itself
+ the TempQueueCleanerUppers.
Modified a test to check whether the sessions are failure listeners of
the new connection after reattachment.
