Fix several crash problems in Debugger.

- When removing a value node in response to ValueNodeChildrenDeleted,
  we need to recurse down and ensure that each node's children are
  likewise notified/removed. Otherwise we end up with deleted child
  nodes in the node table, which in turn led to potential crashes when
  either adjusting a node's type and/or its visible array range.
