Fix typecasting in address->compound node case.

Browse Source 
- In the special case of an address node with a hidden child, we
  must send notifications for removal of the hidden compound's
  children rather than for the hidden node itself. Otherwise the
  base TreeTable's state gets out of sync, leading to a crash when
  attempting to typecast such a node.
