AMQ-9829 Track prefetched messages for duplicate suppression during failover
(#1616)
During failover in transacted sessions with async dispatch (MessageListener),
prefetched messages sitting in the unconsumedMessages buffer were not being
tracked in previouslyDeliveredMessages. This caused them to be incorrectly
identified as duplicates on redelivery and poison-acked to the DLQ.
