value return by job.status is not like in rails

In rails implementation, the job.status was 'state' in case of success and downcased : in the job model:

    # status of the job
    # return either .state or .result (which one is more useful)
    def status
      (((DONE? or ARCHIVED?) and not SUCCESS?) ? result : state).downcase
    end

If we want to maintain outputs we should correct the job.status function.

In my opinion, it is better to keep the 'success' in case of success.
