[Wi-Fi] Show not show Wi-Fi edit UI for never connected open Wi-Fi networks

When users click a Wi-Fi network and it's
WifiConfiguration.getNetworkSelectionStatus().hasEverConnected()
is false, WifiSettings2 will launch the Wi-Fi edit UI for users
to edit password again.
It's not necessary to show the Wi-Fi edit UI if the Wi-Fi network
is a open network.
