qml3d: from user event dynamically created objects are not pickable

// Creating a new cube by clicking cylinder won't printout click event.
// However, if the cube is created dynamically in Component.onCompleted it printouts click event.
// With 'showPicking: true' it can be seen that there's no color(=black) associated to the dynamically created component.
