Update good_job version as well.

  It means that potentially not shut down DJ worker will not be able to
  pick them up for performing during the migration process. After
  migration has been finished the jobs in question will be in
  good_jobs table and delayed_jobs table will be removed. So,
  duplicate execution should not happen.
