[Paraview] Crash of pvserver using pqActiveObjects::instance()

[Utkarsh Ayachit]

pqActiveObjects is not available on the server side. It's a construct
used by the client alone to keep track of what's active. Where is this
call being made? In a filter/reader/writer code? That's not
recommended (rather possible).
