title: Use ember mock server for ember test --server
body: <p>when running <code>ember server</code>, the mocks in <code>server/mocks</code> are served properly, such that they can be used in the tests as well (as the tests are in localhost:4200/tests by default and the api from the mock server is available at localhost:4200/).</p>
  
  <p>However when running <code>ember test --server</code> the mocks are not available which makes tests that rely on those mocks fail. Is this a bug? How to make the mocks available in the test server?</p>
