Merged requested to merge nkoehler/athena:fixSymNSWReco into master
during the MT migration of the CSC conditions access (!26583 (merged)), it was not accounted for the possibility of no CSC chambers (for layouts with 2 NSWs). This MR avoids that the
CscCondDbAlg is created in case the current layout does not have any CSC chamber.
This also fixes the failing
test_Run3_symmetric_fullChain.sh ART test in master.
