Title: Exception when attempting to remove non-owner

For 'npm owner rm', commit 2b39dff0a8245a6a323a5bcbbed2c16a7696bb8c causes a null user to be passed to mutate, which in turn causes a null user to be passed to the mutation. If the user to be removed was not a package owner, this null user value is dereferenced when attempting to report the failure.
