Contour map: Filters are not working

[hhgs]

Cell filter or Property filter is not working, not alone or linked with 3D view.

1. Import a grid model
2. Create a contour map
3. Add a cell or property filter on the contour map view
4. The cell filter is not applied to the contour map

If a property or cell filter is stored in a project file, the cell filter is applied correctly when loading the project. This explains why the regression tests did not catch this error.

It would be nice with a description of how to reproduce the problem.

I have updated the issue description.
