Bug fixes for Run 2 muon triggers

A few bug fixes for the Run 2 muon triggers:
- Correcting the name of the output containers for the CSC decoding tools (so that downstream tools have access to the correct container)
- Pointing the trigger algorithms to use the CSC clusters instead of the PRD collections
- Adding the segment overlap removal (we didn't use this during Run 2, but we probably should have. Adding it now just to make comparisons to the Run 3 triggers, where this is used, easier).
