Issue #26 Add News service and controller

* Change findOne in controller to ask for id instead of newsItemId
* Update route in service to expect id instead of newsId
* Update test for controller to pass the newsItemId to stateParams,
  expect a request that includes /api/v1 and using simple strings to
  concat the id instead of a regex (since it's fixed)
