Make sure we log the last bubble removal

ag/22792413 changed the logic here & returns early so it'd miss
the log statement about the bubble removal. Update the code
to log when the last bubble is dismissed as well.

Additionally we're missing this in the code path for a dismissed
suppressed bubble (pretty edge case), but add the log event in
there as well...

Test: manual - remove last bubble
