Description of problem:
If a message expires in a queue before the HA replicator is able to browse the message, the message will be skipped and not replicated.  This results in the expired message's async completion never being finalized which can stall the original source of the expired message since it will never receive a completion.

Expected results:
While it is not truly necessary for the HA replicating subscription to replicate an expired message, the async completion needs to be finished.
