7438: Shorten hir::TypeParam ranges for traits in NavigationTarget r=matklad a=Veykril

I noticed that selecting `Self` here highlights the entire trait,
![Code_a8DMOEUuWY](https://user-images.githubusercontent.com/3757771/105779993-d2592c00-5f6f-11eb-81d1-bd99f9369cf7.png)
this should cut it down to just the trait name and the `Self` which imo seems better.
