Emit `liveSyncStarted` when the application is really livesynced (#2977)

`liveSyncStarted` event is currently raised before starting initial LiveSync operation. However this makes sense if the name was `liveSyncStarting`.
So move the event at the end of the initialSync logic - this way it will be raised for each device when the LiveSync is really started.
