Bug on render() method concerning renderer_context

[erichaus]

Hello, we are using this package and ran into an issue with our unit tests where it seems that the rest_framework APIRequestFactory which is behind the test client does not pass in a renderer_context:

    def render(self, data, accepted_media_type=None, renderer_context=None):

>       view = renderer_context.get("view", None)
E       AttributeError: 'NoneType' object has no attribute 'get'

/usr/local/lib/python3.5/site-packages/rest_framework_json_api/renderers.py:419: AttributeError

I think you could fix it by doing renderer_context={}

The code from this library will break at the following lines which are not guarded properly:

https://github.com/django-json-api/django-rest-framework-json-api/blob/develop/rest_framework_json_api/renderers.py#L419

also:
https://github.com/django-json-api/django-rest-framework-json-api/blob/develop/rest_framework_json_api/renderers.py#L401
https://github.com/django-json-api/django-rest-framework-json-api/blob/develop/rest_framework_json_api/renderers.py#L420

Here is the corresponding rest_framework.test line that you can see does not include renderer_context as an argument:

https://github.com/tomchristie/django-rest-framework/blob/master/rest_framework/test.py#L183

Let me know if this makes sense or if I'm off course!

Thanks
