DO NOT MERGE Fix issue with bubble stack & bubble data expanded bit being out of sync

If onBackPressed was used while the stack was expanded, it was calling
setExpanded on BubbleStackView (BSV) and NOT BubbleData. This results in
BSV and BubbleData being out of sync which can lead to incorrect behavior.
(e.g. using individual bubble dismiss method instead of the stack dismiss
method).
