Pulp

Description of problem:
There is a discrepancy in response body while doing retrieval of different resource type.
For example when doing retrieval of single unit https://pulp-dev-guide.readthedocs.org/en/latest/integration/rest-api/content/retrieval.html#retrieve-a-single-unit there is no _href in response body,
Meanwhile retrieval of single repo also contains _href in response body.
As an additional info - when doing a generic search for unit https://pulp-dev-guide.readthedocs.org/en/latest/integration/rest-api/content/retrieval.html#search-for-units the response body contains _href.

Version-Release number of selected component (if applicable):

pulp-server-2.4.0-0.2.alpha.git.6.53c19dc.fc19.noarch
How reproducible:

Steps to Reproduce:
1.Retrieve a single unit with GET method with path /pulp/api/v2/content/units/<content_type>/<unit_id>/
2.
3.

Actual results:
_href not present in response body

Expected results:
_href present in the response body
