    dnd: Fix drag cancel animation scale
    
    When a drag is cancelled and the source actor
    is visible, the drag actor is animated back to
    the source position. The scale that the drag
    actor will become is calculated as:
    
        scale = this._dragActor.width /sourceScaledWidth
    
    However, this is wrong; what we wanted to do
    is the opposite:
    
        scale = sourceScaledWidth / this._dragActor.width
    
    Fix the scale calculation to match the math
    above.
