notifier: Handle Manager state when exiting online

Service state can transition from online to disconnect like this:
 1) old online - new disconnect/association => association
 2) old association - new disconnect/disconnect => disconnect

Create a separate function for leaving online mode, don't rely on
the previous old_state in service_indicate_state().

Fixes BMC#25073
