Job submission detection error

[JimCircadian]

The slurm accounting daemon doesn't necessarily register the job quickly enough leading to a narly status. Make it a bit defensive/prettier when the job is yet to be detected:

[23-03-22 15:01:58    :INFO    ] - Submitted job with ID 4448347

This is being caused by the error propogating out of find_job to the batcher itself, which handles it fine. Since it's a bit ugly and is slurm specific, should capture it in there
