Preselection and remote/local rendering can crash ParaView

It is possible to segfault ParaView with a tag mismatch when playing with Remote Render treshold and preselection. unrelated to !4034 (merged)

Steps to reproduce :

  • default settings
  • run pvserver
  • run paraview, connect to pvserver
  • UnstructuredCellTypes, Apply
  • Interactive Select cells on, mouve the mouse around to show a preselection
  • Edit -> Settings -> Render View -> Remote Render Treshold -> set to 0;
  • ParaView is now remote rendering
  • mouve the mouse on the dataset
