Ensure that unacknowledged messages are removed from the Audit so they
are able to be redelivered to another consumer on this connection

> When connected via a failover transport the connection enables its 
> ConnectionAudit by default to filter duplicates.  For messages consumed using 
> a consumer created from a Session in Individual Acknowledgement mode the 
> unacknowledged messages are not removed from the message audit when the 
> consumer is closed.  If a new consumer is opened on that same connection on 
> the same destination the previously delivered messages get tagged as 
> duplicates and are poisoned ack'd.
