add detail_uri_name to Non-PK URL example

This is a crucial detail missing that ought to be included in the example. The resource_uri generated from the example and included in the response is inherently incorrect, given the desired result. EG, if you want to use a non-pk you want to query a ModelResource like this, you'll want the resource_uri updated. If you don't, hopefully you'll notice that the example includes meta.detail_uri_name :)

[DOCS] Update Nested Resources example in cookbook.rst to work properly

The example on Nested Resources in cookbook.rst seems to be from an old version of tastypie, as ``cached_object_get`` expects a ``Bundle`` as its first argument, not a request.

This patch shows how to build a stub bundle to make the example work correctly.  I am not sure if this is the canonical way to build a bundle from a request - in particular, I don't pass in an ``obj``, but then the point of building the bundle is to get the object from ``cached_obj_get`` in the first place. :)

Fixes #984.
Create reverse related resources instead of updating
