setRotation will only work with a delay

[thebino]

changing the orientation with TestButler.setRotation doesn't

// landscape
TestButler.setRotation(Surface.ROTATION_90);
// Thread.sleep(5000);   <-- this will fix it

isLandscapeLayoutVisible();  <-- this will fail if no Thread.sleep is placed after setRotation

// portrait
TestButler.setRotation(Surface.ROTATION_0);
