Title: Allow Preference-Applied header check to include characters before or after the substring

Without this change, a response including other data won't match, e.g.:

```
Preference-Applied: return=representation; include="http://www.w3.org/ns/ldp#PreferMembership http://www.w3.org/ns/ldp#PreferContainment"
```
