[Paraview] vtkPVCameraCueManipulator (0x8353f8e60): Too few keyframes to animate.

[Utkarsh Ayachit]

Can you switch the lines "WriteAnimation" and "CameraAnimationCue.KeyFrame
=...". The WrieAnimation should happen after that. Seems like a bug in the
tracing code. The tracing code is being revamped. Although animation has
been skipped in this revamp, it's on my todo list for subsequent release.
