Fix flakes due to networks obtained via sync APIs
After reconnectWifiIfSupported is called, it is possible that
ConnectivityManager#getAllNetworks does not return the Network, as this
is mixing network callbacks and synchronous calls which is racy (as per
ConnectivityManager javadoc).
Ensure that networks that are reconnected in the test, wifi and
cellular, are obtained through network callbacks through CtsNetUtils.
Other networks are still obtained through the synchronous call, as they
should not change during the test, and there would be no non-racy way to
obtain them otherwise anyway as they are not guaranteed to be connected.
