testSetAirplaneMode verifies the result by checking if intent is
broadcasted or not. The working internet may sometimes remain
connected if the commands processed fast but sometimes don't.
It will leave uncertain network status to the follow-up tests
and cause flaky. This behavior specifically breaks
testRequestNetworkCallback_onUnavailable. As WiFi is not
enabled and still disconnecting, the behavior will confuse
test to not to disconnect WiFi. However, test may still get an
active WiFi network since the WiFi is not disconneted yet. Thus,
verify that working internet should disconnect and reconnect
expectedly if airplane mode is updated.
