rtcds Remove unneeded checks for starting and stopping models.

If models are already started when requested to start, there's no need to check. Systemd won't mind another request to start.
Removing these checks allows the user to specify a list of models to start, stop or restart, and not have to worry if some of them are already
in the requested state.
