Added request param to paginate_queryset in ListModelMixin

[abronets]

In standard PageNumberPagination, paginate_queryset requires request, so this method in ListModelMixin is to be rewritten every time:

def paginate_queryset(self, queryset): return super().paginate_queryset(queryset, self.request)

This code fixes this bug

[sevdog]

The .paginate_queryset which the ListModelMixin is expecting is that of GenericAPIView not any of a pagination class.

This is not required.

TL; DR: mixins are to be used with views/viewsset.

I guess we can close this
