FlowView is crashing

This is a regression introduced by https://codereview.qt-project.org/c/qt/qtdeclarative/+/327669

There is an infinte recursion in QQuickDesignerSupportProperties::propertyNameListForWritableProperties.

This is triggered by items like this:

Item {
 
   id: root
 
    property someType someProperty: Item {
         target: root
     }
}

What happens is that when inspecting all properties of the component (root) it finds someProperty and target is the root item again and its properties will be inspected and there is someType and so on...
