    Revert use of CONF_CHANGED events by test_reattaching_listeners
    
    Reverting part of the change for #14943 and reopening the ticket since this is
    causing frequent Jenkins failures...

      AssertionError: False is not true
    
      ----------------------------------------------------------------------
      Ran 37 tests in 11.423s
    
    Test passes more often that not but at this point the cure is worse than the
    disease, so we should revert until this can be addressed.
