      Steps to Reproduce:
      1. Install pool of 1.4.494 version with forced view changes each 1800 seconds.
      2. Run low load test (10 txn/s) to fill ledger with 500k txns.
      3. Upgrade pool to 1.4.496 version (forced view change interval is not changed).
      4. Run high load test `while true; do python3 perf.py -c 20 -n 1000 -k nym -g pool_transactions_genesis; done`.

      Actual Results:
      View Change was not completed on all of nodes.
      Domain ledger sizes:
       - Node1: 655059, 
       - Node2 and Node3: 700497
       - Node7 700427,
       - The rest 18: 700227.

      Expected Results:
