HLTResultMTByteStreamCnv: Force full event building in debug streams
During Technical Run 4 a bug was discovered when HLT was sending events to HltError debug stream. The stream tag had a ROB ID of HLT result in the ROB list, which triggered partial event building with that single ROB, and the ROB was sometimes missing (in case HLT failed early). The debug stream events should be full events, so instead of adding the HLT result ROB ID to the debug stream tag, we should clear the debug stream tag rob/subdet lists. This change is applied here.
