Quick UI uses qmlpuppet instead of qml / qmlscene / qmlviewer

Steps to reproduce:

• start QC with clean settings, have a Qt / Kit configured
• create a Quick Ui Prototype from wizard template
• check run settings / let it run

Current result:

• QC uses its qmlpuppet to "run" the QML file

Expected result:

• QC uses the qml / qmlscene / qmlviewer from Qt

Not sure if there are any bad implications, just noticed this changed from 10.0 to 11.0.
