Losing jobs on restart while postprocessing

[natefoo]

I can't investigate this fully at the moment but I suspect this is possible because after a job has left the cluster, Pulsar:

1. creates $staging_dir/$job_id/final_status with contents "complete",
2. removes $persistence_dir/${manager}-active-jobs/$job_id,
3. performs postprocessing (writing outputs back to Galaxy), and
4. creates $staging_dir/$job_id/postprocessed.

Because $persistence_dir/${manager}-active-jobs/$job_id is removed before postprocessing completes, it would presumably not attempt to retry postprocessing after a restart.

EDIT: this definitely happens.
