Bug 1312767

Description of problem:
POST /katello/api/organizations request does not return data.

Request:
https://my_server/katello/api/organizations
{"name":"Test_Org_011"}

Response:
{}

For example, when I create similar request for architecture entity, I get some data:
Request
POST https://my_server/api/architectures
{"architecture":{"name":"Test_Arch_011"}}

Response:
{"created_at":"2016-02-29 08:54:53 UTC","updated_at":"2016-02-29 08:54:53 UTC","name":"Test_Arch_011","id":28,"operatingsystems":[],"images":[]}

Or in older versions (6.1.x) we have next output for organization entity:
Request:
https://my_server/katello/api/organizations
{"name":"Test_Org_011"}

Response:
{"ancestry":null,"apply_info_task_id":null,"created_at":"2016-02-29T09:06:28Z","description":null,"id":812,"ignore_types":[],"katello_default":true,"label":"Test_Org_011","name":"Test_Org_011","title":"Test_Org_011","updated_at":"2016-02-29T09:06:28Z","service_levels":[],"service_level":null}
