switch-to-configuration: fix restart of socket activated services

Browse Source 
This fixes two bugs:

* When socket activation is detected, the service itself is added to stop-start list instead of its sockets.
* When service is marked to restart instead of stop (`StopIfChanged = no`) we don't need to restart sockets.
