cros: Fix stacked launcher animations.

In the old version, launching the launcher and then rapidly entering
text and deleting it multiple times caused the scheduled animations to
build up causing the launcher to continue to animate between states long
after text had stopped being entered/removed from the searchbox.

I added a line to stop the current animation before scheduling another
one, which prevents the behavior.
