[vtkusers] fix position of vtkAxesActor

[Nicolas Sarrasin]

  Hi Jim,

When I try to set my interactor according to your steps i get the 
following warnings and my AxesActors aren't displayed :

Generic Warning: In (vktdir)\Widgets\vtkOrientationMarkerWidget.cxx, 
line 533
Set interactor and Enabled before changing       interaction.

ERROR: In (vktdir)\GUISupport\Qt\QVTKWidget.cxx, line 968
QVTKInteractor (028ABC68): QVTKInteractor cannot control the event loop.

Any idea ?
