Component/Component3D not created correctly

Tested on Windows with QDS 4.8 snapshot 385 (project storage build)
Steps to reproduce:

• Create a 3D project
• Add Component3D from Components view to Navigator
• Exepected is that Component3D with child node is created:

    Component {
        id: component3D
        Node {
            id: componentRoot
        }
    } 

• Result: No child node is created and Code view shows warning "Components require a child element":

        Component {
        id: component3D
    } 

• Reproduces also with (2D) Component item.
