Specify which callback is unexpected in testMobileDataPreferredUids

This test is flaky due to assertNoCallback(). Because this
method expects no any callback received but the wifi network
may update its capabilities during testing and trigger
onCapabilitiesChanged() to cause test failed. Thus, these
callbacks should be ignored in the tests.

Replace the assertNoCallback to assertNoCallbackThat with
callback type specified to deflake tests.

Also align the available callback verification in the test to
avoid confusion.
