NetworkListStoreData: Fix badly formed WifiConfiguration

The network config created by the app_XXX in the associated bug had
preSharedKey set, but did not have KeyMgmt.WPA_PSK bit set. It instead
had a KeyMgmt.OSEN bit set (which is not even public, so not sure why
the app is setting that). The user has a saved network with the same SSID in
the XML file. So it looks like the app tried to add the same network
back for some reason, but it had the wrong bits set in KeyMgmt. So, we
ended up creating a different network with configKey set to "SSID"NONE.
This was stored in the XML file, but when the user upgraded to a build
containing ag/10449860, the calculated configKey became "SSID"OSEN
which did not match the configKey stored in the XML file. Hence the
parsing logic errored out.

2 fixes added:
a) Add a generic correction logic in XML file parsing logic to reset
the KeyMgmt to WPA_PSK if it detects a preSharedKey, but KeyMgmt not
set appropriately.
b) Apply the same fix in validate() method. We could have error'ed
out here because it is an invalid WifiConfiguration. But, fixing
in-place will avoid a lot of app compatibility issues.
