Raytrace button status error

[Hildo Guillardi Júnior]

Raytrace button doesn't start pressed if the 3D viewer open with ray-tracing already active.

To reproduce:

1) Draw something in the Pcbnew;
2) Go to 3D viewer;
3) Active the Raytracing by the button at the bar;
4) Close the window (3D Viewer);
5) Re-open the 3D viewer;
6) See that, despite the raytracing is active, the button is not pressed.
