[vtkusers] fix position of vtkAxesActor

[Jim Peterson]

I Am not sure if this is a factor based on the information provided, but 
it appears the vtkOrientationMarkerWidget expects the 
renderWindowInteractor to be connected to the RenderWindow before widget 
is connected to the RenderWindowInteractor.  At least that appears to be 
the controlling factor from my Java implementations.

in other words, Widget.SetInteractor() prior to 
RenderWindow.SetInteractor() or RenderWindowInteractor.SetRenderWindow() 
fails. Widget.SetInteractor() after either of the other functions works.

HTH,
Jim
