Fix potential NPE & clean up some logic
- I had accidentally swapped the values in removeBubblesForUser
in one place which could lead to a crash, it's actually simpler
to just do the removal there since it's the parentUser that was
removed so we can remove all of those entries.
- In other places I've added a null check before performing the
removeIf to be safe
- Added a test checking bad input
