[ATR-25992] In-view legacy EDM muon container not managing its content
Looks to be an oversight from early migration work, removing muonCandidate->clear( SG::VIEW_ELEMENTS );
as otherwise nothing is taking ownership of the new MuonCombined::MuonCandidate(msLink, (*extTrackLink)->trackLink(), (*extTrackLink)->index())
Checked with RunTrigART.py
