Title: Implement extractHasMany and extractBelongsTo on FixtureAdapter

Enable fixtures to load relationships. It was omitted in 96de4d5b88d1156ee9ee743dad39b2be5b1da90e. This PR add a test and fix it.

I made another PR to enforce more methods on the serializer (#717) in order to prevent this kind of problems in the future
