Attempting to get the wrapped MuonConfig working again in RecExCommon
At some point recently this stopped working. This isn't the complete fix but I want to get this in so others can check (since I'm changing configuration that I'm not too knowledgeable on)
The problem was I was getting clashes between e.g. LArVolumeBuilderCond in CA/old configuration. And incidentally, the fact that the non-cond CaloTrackingGeometryBuilder was getting Cond sub-tools I consider a bug, but a benign one.
