Bug 36495: Use render_resource_deleted() helper everywhere

This patch makes the API controllers use the render_resource_deleted() helper.

No behavior changes are expected.

To test:
1. Apply this patch
2. Run:
   $ ktd --shell
  k$ prove t/db_dependent/api/v1
=> SUCCESS: Nothing broke
3. Sign off :-D
