Suppress the bubble animation on updates

When a bubble is updated, we now suppress the animation when needed.
This prevents the animation from playing on the lock screen, when
the shade is open, when the IME is visible, etc.

Note that for new bubbles we were already suppressing the animation.
The issue fixed by this change is only observed for updated bubbles.
