fix: move extension handling outside of tree

Fix #400

BREAKING CHANGE: `Tree` and `PrefixTree` insert method expects a path without the file
extension. They also expect the fullpath of the file as a second
argument (it used to be optional). This aligns better with their responsibility.

```ts
// replace
tree.insert('file.vue')
// with
tree.insert('file', resolve('file.vue'))
```

This shouldn't affect most users as the Tree implementation are used
internally to represent the folder structure.
