UI: move some logic to constructors

Some code cleanup while reading through the code:

On vogleditor_apiCallTreeItem construction if the object is
constructed with a parent then the client must add the new
object to the object's parent's child list after the object is
constructed.

Instead of the client having to do this for the object, it's now
done in the object's constructor.
