InDetPerformanceRTT: fix switch configuration for ART tests
Corrects switch configuration for running InDetPerformanceRTT_jobOptions with calo-seeded bremfit. Fixes ATLIDTRKCP-162.
prior to this fix, the jobs run-time crash when InDetCaloClusterROISelector attempts to retrieve container: /afs/cern.ch/work/l/lmijovic/public/idart_mr_ROI/crash_repro.out
after this fix the InDetCaloClusterROISelector container retrieval (and the full job) runs fine: /afs/cern.ch/work/l/lmijovic/public/idart_mr_ROI/updated.out
When this is merged, we should likely have InDetPerformanceRTT ART in master,centos7 running reco successfuly.
