AnalysisTop: retrieving tools for soft muon OR only when needed

This prevents some weir error that we encounter when running over TRUTH1 derivations:

This points to some underlying issue with the code. We should be able to retrieve the tool even when not using soft muons. So the changes here just hide the problem, but at least allow to run for the usual cases.
