software/theia: Don't process instances on restart

Do not process embedded instances when theia's standalone service is
(re)started, e.g. when theia is upgraded or after rebooting.

Doing so before caused embedded services to start even when autorun
was otherwise stopped, i.e. autorun=stopped was not a guarantee that
the embedded instances would never be processed.
