WPS NFC: Connect using learnt credential after NFC Tag read

Browse source 
Instead of just adding the new network, prefer the network learnt from a
configuration token during the first connection attempt. This makes the
WPS NFC case behave similarly to the in-band provisioning cases if there
are more preferred networks in the scan results.
