[Paraview] Use one statefile for multiple time values

[Eelco van Vliet]

Hi Utkarsh,

I am using the LegacyVTKReader. Looking at the reader properties I see that
indeed the new filename is in the reader object, but still the first file as
defined in the state file is used for plotting.

Regards
Eelco
