Vinit Deshpande fcd4612f70 Fix access point list jumping around in WifiSettings
This happens because the scan times are very aggressive
(to save power); and we don't find all APs on each scan.
So on each scan, some APs are considered lost and some
other are considered found; resulting in reordering the
list.

This change fixes that by requiring 3 scans to confirm
absence of an AP.
