Error fix of inconsistent in TrigL2MuonOverlapRemover for more than two objects, ATR-20360
I want to merge this change into the master.
An error message was sent if the overlap removal of more than two objects was inconsistent. However, in this case, the original code (not the MT code) does not give an error message (warning instead of an error), leaves all TEs active and sends them to the next algorithm. Therefore, I modified the MT code like that.
