fix for bjet_ALLTe and METfromJet tests; removed obsolete photonMenuDefs.py

some fix for ART tests failures, as in https://its.cern.ch/jira/browse/ATR-19843 and https://its.cern.ch/jira/browse/ATR-19900 I still see many ART tests failing (not the primaries for the CI), but this will be tracked by experts.
