This seems inconsistent according to the current ember-data docs: https://github.com/emberjs/data#fetching-a-single-model

I'll check if this is easy solving.

The problem here Ember Data doesn't have an easy way to include query parameters when fetching a single record.

but knowing this is fetching a single model this objectAt(0) fn might be already included on the given promise, maybe.
