[Paraview] ParaView 3.6 animation script causes a segmentation fault

[Utkarsh Ayachit]

You need to set the animated proxy on the cue. Not sure how this could have
worked in 3.4 either.

<snip>
cue = servermanager.animation.KeyFrameAnimationCue()
cue.StartTime = 0.0
cue.EndTime = 1.0
cue.AnimatedProxy = view
movie.Cues.append(cue)
</snip>
