I'm not sure what exactly has caused this, but an early state change is
now happening before the D-Bus interface is ready for it. I tried to
reorder the steps a bit to avoid this, but that seemed to require more
changes that I wanted to do at this point. It looks like it is fine to
just drop the first state change signal and handle this by minimal code
change that makes the D-Bus code skip the signals that may happen before
initialization has been completed. The only signal that I noticed was
this wpa_state change from its default value (WPA_DISCONNECTED) to
WPA_INACTIVE when the configuration file does not include any enabled
