Some rules are not instantiated

[smirolo]

When using saas.decorators.fail_direct as a rule, the various RoleDescription in the database for which organization_id is NULL are not showing up as options in the rules dashboard.

The problem stems from this query in rules.views.app:

                    try:
                        queryset = cls.objects.filter(
                            organization=self.app.account)
                    except FieldError:
                        queryset = cls.objects.all()

role descriptions which are global by nature use organization_id == NULL so the queryset returned is empty here. We cannot blindly add the is_null condition either otherwise a duplicate rule is created for Direct Managers - once through the queryset and once through fail_direct_strong.
