-------------------------------------

A unit test for this would be a good start.

> 1. Create and start consumer
> 2. Messages are delivered and queued in unconsumed messages
> 3. Listener is added
> 4. Messages are Redispatched
> 5. Messages are considered duplicates
> Succestion:
> Have a cleare state of messages in the unconsumed messages. Either they should be in the connections duplicate list or not.
> If they are in the in the dup list. then rollback dup whenever a message is redispatched.
> If not check dup before deliver to message to the client. (Receive/Deliver to Listener)
> This makes it much easier to get a correct code then currently where unconsumed messages can either be in the dup list or not.
