Delay deletion of the history store record to reconciliation

    Description

      In prepared rollback of the onpage value, we restore the latest value we wrote to the history store. If the checkpoint is running at the time, we will not delete the restored value from the history store. This causes triggering out of order fix when the restored value is written to the history store again. However, if checkpoint is running at the time, it will panic the system as handling out of order timestamp fix is not allowed.
