Objects passed to template are not EasyInstance instances

When loading `http://localhost:8000/browse/app/model/`, it correctly prints a list of objects, but they all link to `http://localhost:8000/browse/app/model` (instead of `http://localhost:8000/browse/app/model/objects/X`)

It looks like the objects passed to the template `model_detail.html` are not `EasyInstance` instances, which is why `object.url` is empty. The objects are simply instances of the Django model.

After a bit of debugging, I found out that the `iterator` method of `EasyQuerySet` is never called, so that we end up with an `EasyQuerySet` that contains Django model instances (in `EasyModel.objects`).

This is with Django 1.11.7 and Python 3.6
