Muon view algs to access RoI collections inside their views

I don't think it should create any actual differences, but the muon algorithms running inside views were often accessing the RoI collection outside of that view. I have now changed that.

Potentially could change results where there are multiple RoIs in the outside-view collection, but only one within the view?

Algorithms within a view accidentally accessing an out-of-view container is a potential source of error, although is fine if intended. I've been searching for accidental cases.
