Node failure job with no return_code file still marked as successful in Galaxy

[natefoo]

Running hifiasm on the VGP instance and the node it executed on appears to have failed and the job was terminated prematurely. As a result, nothing past a certain point in the job script was executed, including capturing/writing the tool return code to return_code. Despite this, none of the postprocessing failures were fatal (due to being work_dir outputs) and for some reason, Galaxy still treated this job as successful.
