Request object missing from Django authentication

[ripal-pm]

Hi,

First of all, thanks for creating this toolkit and hope this request will expand it's usage.

Many third party AUTHENTICATION_BACKENDS requires request object. This toolkit is not passing request object to django.contrib.auth.authenticate(). If you will update oauth2_validators.py=>validate_user's authenticate call from authenticate(username=username, password=password) to authenticate(request=request, username=username, password=password) will fix this issue.

Hope you will be able to make this change quickly.

Thanks with best regards,

Fixed in #643 I believe.
