Closes #1205
Pass a string, not the type, to buildURL

This will make subclassing, munging the type, and calling super work
more sanely.
Changes extractSingle's return to call this._super

This makes the example in-line with the current documentation of DS.RESTSerializer.
I also was having trouble making extractSingle work in my application and making this change fixed it.
