    Fix a failure to respond to children-changed events in some cases
    
    When a children-changed event is received, the cache of children should
    be updated if present.  However, to test this, the code was checking for
    the presence of a non-NULL list of children, which would be the case if
    the object initially had 0 children.  The correct thing to do is to
    check the accessible's cached_properties.
