Fix network name for Passpoint network

Metered network settings (Settings -> Data Usage -> Network Restrictions)
show different network name for passpoint networks than saved networks
(Settings -> Wi-Fi). This is because it shows only SSID for all networks
which for passpoint networks may be different than provider friendly name.

It should instead show AccessPoint#getConfigName as displayed in the
list of saved networks.
