Add hasOne.find association
Add find options:
* noInstanceEndpoint: true - resolves get requests for you by checking the terms. It assumes you have received a collection back, because your backend has no endpoint to return individual instances. It will parse the results for you on the front-end. Usually, this is left to the backend.

* forceGET: true - Ignores cached copies of the model, and forces an HTTP request to retrieve backend instances.
Add tests for new find methods
