Fix figure not properly closed in CodeExercise with parameters

When a CodeExercise with parameters is created the `<Figure size 640x480
with 0 Axes>` the CueFigure is created. I am not sure why this happens.
It could be related to interact. It can be fixed by moving the CueFigure
creation before the ParameterPanel creation
