Fix flaky test: testMobileDataPreferredUids
The test is flaky because the wifi network unexpectedly sent a
link properties change before switching the default network to
cellular. To fix this problem, change to eventuallyExpect(),
which can ignore the randomly triggered callbacks and wait for
the expected callback.
