Fix some more empty bubble issues!
The main thing here is not ignoring new selected bubbles that are different instances, but otherwise equal (same key, etc.). Also, release the animating-out surface on collapse, and don't start the switch animation if we're collapsed. I was able to cause some issues in my testing with animating-out surfaces lying around. Bug: 159861400 Test: manual, also using modded bubble test app with instantly canceled+readded bubbles Change-Id: Ic19ee0bd3f4700021b1c790ae267beba9a52c532
