[flexiglass] Parameterize QuickQSPanelControllerTest failures with SceneContainerFlag

Also fixed the test exception: `java.lang.IllegalStateException:
should be called from the main thread. sMainLooper.threadName=main
Thread.currentThread()=Instr: android.testing.TestableInstrumentation`.

To ensure that the test setup and execution run on the main thread,
this cl added the @RunWithLooper(setAsMainLooper = true) annotation.
