> When a client with a durable consumer loses its connection to the broker and reconnects using the failover transport it does not receive any Messages that it had not ack'd before it failed.
> Testing shows that older client's that don't recover their Consumers by sending a ConsumerInfo command with a zero prefecth followed by a ConsumerControl Command with the old prefetch value recover their unacknowledged messages.  
> Test case attached
