Fix AnimationDrawable double-start bug

AnimationDrawable.setVisible(true, true) was not correctly recording
the fact that it had started the animation, so it was possible to call
start(0 immediately afterwards and have two animations running on the
drawable in parallel, resulting in incorrect frame ordering.
