Closed requested to merge hpacey/mcjoboptions:HHH_ControlFix_230127 into master
Description of bug
Fixing a bug where the attempt to find the physics short name in the control file failed.
Rather than finding it via the JO filename via the JOconfig (which failed because that now only gives the dsid foldername rather than a full path to the JO files) We simply directly call for the physics_short name.
tested locally with same setup used in other tests for this request
