Fixed incorrect usage of nested resources

I hope I got it right. :smiley: This is the thing with [nested resources](http://emberjs.com/guides/routing/defining-your-routes/) not inheriting the parent name in their route name. I.e. a `bar` resource under a `foo` resource would have its children be bar.*, not foo.bar.*, according to the referenced page. (in the "Nested resources" section of that page)
