End screenshot animation early on layout change

If the phone configuration changes (e.g. we switch orientations)
mid-animation into the corner, the destination bounds are no longer
correct, so we end up in a weird state. Ending the screenshot
animation early on configuration changes fixes this problem.

Bug: 190545541
Fix: 190545541
Test: manual (take screenshot in landscape, rotate while animation
is happening, observe results)
