EditColumn shortcuts can't specify call target for `field`

[boxed]

I had this EditColumn shortcut:

    @classmethod
    @with_defaults(
        bulk__call_target__attribute='image',
        filter__call_target__attribute='image',
        field__call_target__attribute='image',
    )
    def image(cls, **kwargs):
        return cls.foreign_key(**kwargs)

It crashes with

TypeError at ...
Field object has no refinable attribute(s): "call_target".
Available attributes:

Also, in EditColumn.refine_done it sets self.field = None which seems a bit weird. I would expect that to be the field, and that it's available in evaluate parameters.

I was unable to reproduce. This works:

@pytest.mark.django_db
def test_call_target():
    class MyEditColumn(EditColumn):
        @classmethod
        @with_defaults(
            bulk__call_target__attribute='image',
            filter__call_target__attribute='image',
            field__call_target__attribute='image',
        )
        def image(cls, **kwargs):
            return cls.foreign_key(**kwargs)

    f = MyEditColumn.image(model_field=TBar.foo.field).refine_done()

I think this is since the .field is just the template for the edit field and the create field. Not something that should actually go on the EditColumn once it is instantiated.
