make sure master restarts dsService if twill services are already running

Issue is this: If the master becomes leader, it checks whether twill services are running. 
- If not, it starts the twill services, and once they are running also starts the dsService
- I yes, it simply leaves them running and does nothing. But it must start the dsService. 
Hah. I had a hunch that that would be needed... knew that you would catch me. :)
