Fix RulesObjectType

graphql.error.graphql_error.GraphQLError: RulesObjectType.get_queryset() missing 1 required positional argument: 'perm'

assigned to @ZugBahnHof

created branch 1097-fix-rulesobjecttype to address this issue

mentioned in merge request !1584 (closed)

Proposed fix:

class RulesObjectType(DjangoObjectType):
    class Meta:
        abstract = True

    @classmethod
    def get_queryset(cls, queryset, info):
        q = super().get_queryset(queryset, info)

        if not hasattr(cls._meta, "queryset_rule") or getattr(cls._meta, "queryset_rule") is None:
            raise NotImplementedError(
                f"Graphql type {cls.__name__} implementing RulesObjectType must provide a queryset_rule via Meta.",
            )

        return queryset_rules_filter(info.context, q, getattr(cls._meta, "queryset_rule"))

Sadly does not work, because for some reason, cls._meta does not recognize meta attributes that are set in the subclass but not in the parent class, but due to abstract = True I cannot set the attribute myself…

RulesObjectType is currently not used anywhere within AlekSIS (probably also due to it not being broken)
