[Paraview] ParaView 3.12: state of calculated variables not restored

[Utkarsh Ayachit]

Can you try reproducing with 3.14.0 and using a default reader e..g
opening disk_out_ref.ex2? I tried with 3.14.0 and doing something
similar with disl_out_ref.ex2 and had no issues loading the calculated
variables.
