In WifiSettings, invocation of onConnectedChanged should not update
access points. This is controller by another callback,
onAccessPointsChanged. Furthermore, this is fired before any changes
have even been made to the AccessPoints.
This is exacerbating a problem where old scan results are not shown in
the WifiPicker, or sometimes the platform does not return any scan
results.
