Resolve ATLTAU-1769
Fixes issue accessing event containers used by tau truth matching.
Calling TauTruthMatchingTool::getTruth(xtau,truthTausEvents) will store pointers to containers in TruthTausEvent enum which is passed as parameter. Truth matching previously used member TruthTausEvent enum in truth matching which would have been empty.
