Description (last modified by Tim Graham)

Setting attributes on deferred objects (DeferredAttribute) should trigger original field's descriptor's __set__() (if any).
Currently, specially for custom fields set up as descriptors defining __set__(), the original field's __set__ is never called when setting object attributes on deferred fields.

The patch failes as DeferredAttribute no longer has model_ref. On a side note, {{{_meta.get_field_by_name}} can be used instead of iterating.

@Kronuz, is the issue still relevant (I was thinking 7f51876f99851fdc3fef63aecdfbcffa199c26b9 might have helped)? If so, can you update the patch and add a test? Or at least add some more concrete steps to reproduce to help someone else contribute to the issue?
