Fix b/248686898: Battery Usage list renders items on top of each other after swiping back from an app

Root cause: When adding an animation to the hourly chartview which is scolled up out of the page, onBindViewHolder() will be trigered, then UI is refreshed again, and then the animation is added to the hourly charview again. This is a dead loop.

This fix adds animation to the hourly chartview only if the visibility is changed.
