[BUG] User Registration Bug

[Preet-Sojitra]

Whenever user registers ( at this url http://127.0.0.1:8000/register/) by username and password instead of signing up with google it throws an error saying
You have multiple authentication backends configured and therefore must provide the 'backend' argument or set the 'backend' attribute on the user.

This is happening most probably because of the authentication using google.
