Fix testTetheringUpstream flaky

testTetheringUpstream test case need cellular network. So it disable
wifi and getActiveNetwork to check whether current network is cellular.
But there is a race that call getActiveNetwork right away after
disconnect wifi. getActiveNetwork may return null because switching
network is not ready yet.
