Try to fix IME multi-display tests flaky
There's a chance that IMS moves from the default display to the first
simulated display and receives #onConfigurationChanged callback,
which makes the test flaky.
This CL changes to verify #onConfigurationChanged callback when top
focused display is movd to the first display to reduce flakiness.
Test: forrest run testNoConfigurationChangedWhenSwitchBetweenTwoIdenticalDisplays * 100
