Scrolling with mousewheel in ListView does not produce onMovementStarted events

To reproduce, use examples/listview/listview-example.qml and add the following snippet to one of the listviews:

onMovementStarted:

{ console.log("onMovementStarted()") }

onMovementEnded:

{ console.log("onMovementEnded()") }

onMovingChanged:

{ console.log("onMovingChanged()") }

Nothing is printed on output if scrollwheel is used, but it works with mouse. Other signals are broken too as can be seen from the output.
