Changed
- Use `Authorization` header for `USERINFO` instead of request param
- `token` field in `BlacklistedToken` table changed from `TextField` to `CharField(max_length=15000)` for MySql compatibility
Fixed
- register json web keys to session only if not already registered
- fix error handling by adding required method parameter
- `email`, `first_name` and `last_name` cannot be None. Fallback to empty string.
- correctly check for status code ok when getting access token.
