#69 - JWT Tokens could not be returned after regiserUser mutation

- This updates the mutations to expect a User model to be passed through instead of a WP_User object
- This also updates some of the errors to be more clear, passing through WP_Error messages
- This also returns null when the user cannot access the JWT Secret instead of throwing an error.
