WIP: Add tests and make sure that headers are set

* We realized that headers were not set whenever we give 204
  because `render_api_error!` doesn't preserve the headers.

* We also realized that `update_runner_info` would be called in
  POST /builds/register every time therefore runner is updated
  every time, ticking the queue, making this last_update didn't
  work very well, and the test would be failing due to that.
