django-oauth-toolkit tries to parse all requests' body

[sassanh]

I'm using django-oauth-toolkit with django-rest-framework, I wanna send a bulk create request to django-rest-framework something like:

curl -X POST 'http://localhost:8000/api/user/' -d '[{"firstname":"John","lastname":"Oliver"},{"firstname":"X","lastname":"Y"}]' -H 'content-type: application/json'

When I send this request it never reaches to django-rest-framework because django-oauth-toolkit is trying to parse that request while it's not even sent to /o/token/ and it expects the request body to be a dict not a list. django-oauth-toolit parses every request no matter what's the endpoint.

I created a PR for this issue, the PR ignores the request if it can't parse it as a json dict.
