Subject: [PATCH] Fix warning when running tox -e api-ref

Running `tox -e api-ref` prints warning:

  WARNING:test command found but not installed in testenv
    cmd: /bin/rm
    env: /opt/stack/keystone/.tox/api-ref
  Maybe you forgot to specify a dependency? See also the whitelist_externals envconfig setting.
