Need to sort MongoDb highest seqNr using only the seqNr, not ordering #344

This query may not return the actual highest seqNr if PersistAsync is being used and Mongo processes parallel transactions in arbitrary orders. Need to use the combo of PersistentId and SeqNr (descending) instead.

Nevermind, this code was for replaying tags - not individual persistence ids.
