viewer#2985 Odd crash when notifying voice observers

Crash points at enableDisableCallBtn, but button's floater was cleaned
earlier and has a removeObserver call so an observer record should be
long gone. Likely something else is going on.
Went over various callbacks and made sure they are cleaned. But in case
floater somehow remained, added mSession = nullptr.
