Review comment:
Even that logic to create ValidWriteIdList based on all repl opened txns
isn't right as it says that stats are valid for all these open txns but it
isn't. Also, it sets high water mark based on 0th index in the replTxnsList map
which might be pointing to wrong writeId compared to current txn's writeId. So,
I doubt, this logic should be anyways removed.
