android: 2.14.2 - fix network label showing cellular while on Wi-Fi

underlyingNetworkLabel() returned the first non-VPN network from
allNetworks, whose order is unspecified - Android keeps the cellular
network agent alive in parallel with Wi-Fi, so on Wi-Fi the details
sheet could show "Сотовая сеть".  Wi-Fi now wins when present (same
precedence as NetworkMonitor's trust decision); cellular is only
reported when no Wi-Fi network exists.
