Improvement of MuonCondAlg configs and MdtCondDbData bugfix
Improvement of the old-style and new-style muon configurations for the MuonCondAlg package in the spirit of the bugfix for the run1 setup made by Scott in !26231 (merged). Also fixing a typo for the CSC folder in the new-style config (its the CSC_OFL not the DCS_OFL scheme). Furthermore fixing a bug that hasn't been noticed yet (but will be a problem when the MdtCondDbData::isGoodChannel function is called): MdtCondDbData cannot hold the ref to the MdtIdHelper, instead it must be passed to the relevant method when invoked.
