https://issues.apache.org/jira/browse/AMQ-3193 - fix regression with spring listener test. IndirectMessageRef cannot do equals bc it will break composite destination delivery to a single consumer, possible to break inflight count as ack of one message removes others from dispatched when message ref matches in error. 

Fix is to ensure message ref is passed about such that there is a single ref per message. rework some internals to pass ref rather than message.
