Major Description
When addressing QPID-3014 it was noticed that the Session and Connector actors were not being set appropriately when processing events arriving on 0-10 connections. As a result, logging such as session close and connection close do not properly convey the associated LogActor, and instead reported either the actor for the wrong connection that was previously left on the CurrentAActor stack, or jsut the default Broker actor supplied when the stack is empty.
