commit script broken

Look like the recent MR !252 (merged) broke the commit script, since it's doesn't accept JOs and gridpacks apparently:

Checking jO consistency and DSID ranges ...
	950xxx/950031/mc.Sh_228_ttbar_dilepton_FusingFragFix_valid.py  in correct DSID range
New DSID directory: 950xxx/950031 ...
	OK: log.generate file found.
	OK: log.generate file contains no errors
	OK: CI job expected to last less than 1h - time estimate: 0.05 hours
	Will now add files to git commit
		File: log.generate cannot be added to the commit. Skipping.

		File: mc_13TeV.Sh_228_ttbar_AllHadronic_EnhMaxHTavrgTopPT.GRID.tar.gz cannot be added to the commit. Skipping.

This was found in !256 (merged).
