DEV-164: Added sails call to init version updates

Fixes bug introduced in PR 166 (ArekSredzki#166). The issue is that `/versions/sorted` (changed at line 537 of `data-service.js`) is not a proper blueprint api call and doesn’t initiate web sockets properly to monitor for updates to the version records.
