      Currently we  always return  ChangeSyncSourceAction::kStopSyncingAndEnqueueLastBatch

      https://github.com/10gen/mongo/blob/42cf5a3e894215adc52c615b80ab01d797f25d92/src/mongo/db/repl/replication_coordinator_impl.cpp#L5030

      However, there  are  some  cases, such as the linked  BF, where we should actually not  enqueue the final batch. Handle these cases and return the proper  error code so that we do not  apply a  batch that we  should  not.
