Fix a bug of SCTLorentzMonAlg_test.py

athena.py SCT_Monitoring/SCTLorentzMonAlg_test.py

gave

ImportError: No module named SCTLorentzMonAlg

This error was introduced at MR !24373 (merged). This error is fixed by this MR.

However, I still get another error:

L1TopoConfigSvc      INFO XML file: L1Topoconfig_LS2_v1_22.0.3.xml
L1TopoConfigSvc     FATAL in sysInitialize(): standard std::exception is caught
L1TopoConfigSvc     ERROR L1Topoconfig_LS2_v1_22.0.3.xml: cannot open file
ServiceManager      ERROR Unable to initialize service "L1TopoConfigSvc"
TrigConfigSvc.S...  ERROR ServiceLocatorHelper::service: can not locate service TrigConf::L1TopoConfigSvc/L1TopoConfigSvc
TrigConfigSvc       FATAL failed to retrieve L1TopoConfigSvc: ServiceHandle('TrigConf::L1TopoConfigSvc/L1TopoConfigSvc')
ServiceManager      ERROR Unable to initialize service "TrigConfigSvc"

I think this is a trigger problem. --> A comment was posted in https://its.cern.ch/jira/browse/ATLASDQ-721
