Two small fixes for commit script

Description of bug

• Actual call to logParser from commit script is python3 scripts/logParser.py -c -i $dsiddir/$dsid/log.generate -j $joFile while the call when an error is found is misses the -j part. This means that on rare occasions (when the jO file is changed since log.generate is created???) you can actually have something like this:

while if you run with -j you see the error:

Changes introduced

• Harmonise call to logParser when checking for errors and when printing them out.
• Also keeping only the first occurence of atlas-physics/pmg/mcjoboptions.git when finding remote branch name, so that cases like this are handled more cleanly (this is not really a bug since picking any of the two remote names would lead to exactly the same behaviour)
