versions resource on volume api endpoint fails

[Chuck Thier]

When osapi_volume is added to enabled endpoints, requests to that endpoint fail.

For example when issuing a GET to / to get the versions, the following is returned:

    makes volume versions display properly

     * The compute versions controller changed during a refactor and broke
