QFJ-790: Logout message not propagated to the fromAdmin() callback
 - changed logic in event handling strategies to enqueue an END_OF_STREAM message instead of stopping to process messages when the responder has been removed
 - callback sessionClosed in AbstractIoHandler no longer will concurrently disconnect the Session (this also lead to deadlock problems in the past) but also enqueue an END_OF_STREAM message
 - the Session will disconnect upon reception of an END_OF_STREAM message
