core: only persist explicit managed state in device's state file

Browse Source 
For example, when starting without Wi-Fi plugin, a generic device
is created. On stop, we should not store the unmanaged state
on the state file, otherwise after restart the device is unmanaged.

Only store explicit user decisions.
