Restore the null behavior of buildWifiTemplate
The old behavior was to only return those wifis that have
a null key/subscriber ID (e.g. not carrier wifi). To keep
backward compatibility, restore that behavior.
Also only crash the old methods on devices with initial
SDK U, because it can't be mandated that devices that
upgrade must not call these methods.
