Don't animate black background on cold launch from launcher 

When animating cold start from launcher we can't compute the
progress in SurfaceControlWithBackground#calculateBgCrop() via
tracking status bar insets. This CL won't animate bg crop
in case the progress does not make sense.

Bug: 64598822
Test: Cold launch letterboxed app from launcher.
