Avoid panic with outline highlight ranges

Previously we were using a function in `editor` to combine syntax
highlighting and fuzzy match positions, it would operate on the full
text as put into the label. However we now have a method `ranges` on
`StringMatch` itself which operates on just the match text.

The outline view has some pretty specific behavior around path/normal
matches and how they are highlighted. So let's just give the match the
full text before it leaves the search function so it can freely index
