Previously (in NM 0.8.x) most WiFi connection were from user settings service.
And the service updated 'seen-bssids' property when got connected.
But the settings service in 0.9 don't do that. That inhibits auto-connecting to
hidden networks. This commit takes care of updating 'seen-bssids'. However, we
don't want to write out the conection each time it's activated (touching /etc).
So, seen BSSIDs are kept separately from the connection in a look-aside file.
