Fix set-quotas for non-project scoped tokens

Previously, if set-quotas was called with a non-project scoped token and the all-projects flag was not set, the quotas would be updated but the result returned
would always be the default quota values.
This patch changes the API to require the all-projects flag when set-quota is called and the token is not project scoped.
