Permission check with multiple roles changes underlying grants model.

[aleclerc]

The following simple test fails, and actually changes the underlying grant model.

    it('Check with multiple roles changes grant list', function () {
        var ac = new AccessControl(grantList);

        // Admin can update any video
        expect(ac.can(['admin']).updateAny('video').granted).toEqual(true);

        // console.log('grants', ac.getGrants());

        // This check actually changes the underlying grants
        ac.can(['user', 'admin']).updateOwn('video');

        // console.log('grants', ac.getGrants());

        // Admin can update any video (nope not anymore!)
        expect(ac.can(['admin']).updateAny('video').granted).toEqual(true);
    });
