  2. Modify the salvageRevisionCounterDisabledReplicas logic 

    The old logic is that:
1. Filter replica candidates to keep only replicas which was modified
   within the last 5 seconds from the last modified replica
2. Then filter to keep only replicas with head size equals to the biggest
   one
3. Then pick a random replica from the set

The new logic:
1. Filter replica candiates to keep only replicas which was modified
   within the last 5 seconds from the last modified replica
2. Then filter to keep only replicas with head size equal to the biggest
   one
3. Then pick the last modified replica from the set
