cleanup of TauAODLeptonRemovalTool in tau reconstruction

This MR is meant to cleanup the TauAODMuonRemovalTool which is used in the MuonOLR tau reconstruction. The code was originally meant to be used for both elecOLR and muonOLR objects, but it's actually only used in the muon case. Therefore, the code has been cleaned from all references to electron treatment and also the Tool name was changed in "TauAODMuonRemovalTool" to clarify better its usage in Tau reconstruction.

No output changes are expected
