Fixed support of multiple sites

The new version of a hack is somehow different. Though, it attempts to
do the same trick altering the underlying connection, it does a
reconnect instead of just patching the URL. As a result, this allows
different resources to work with distinct `site`s at the same time.

See [related upstream issue](
  JsonApiClient/json_api_client#215
) for details.
