http(s)://app-domain/auth/done will throw error

If you access directly http(s)://app-domain/auth/done that will give this error:

Exception Type: MultiValueDictKeyError at /auth/done/
Exception Value: "'code'"

This exception should be handled in that view, redirecting to some default location when code is not available, don't you think?

code = request.GET["code"],
