Title: Allow exact string matches to return an empty object instead of null

We want to be able to iterate over a collection of patterns, some of which don't actually contain values to extract. This patch solves that problem, returning `{}` instead of `null` for exact string matches.

```coffee
patterns = [
"/apps"
"/apps/{app}/resources"
"/apps/{app}/settings"
"/addons/{addon}+{plan}"
]
```
