sh:class with 0 count still present in the filtered shape

[Voldenuix]

The filter command doesn't delete the sh:class with 0 count in the filtered shape.
While it's not really a problem in some usage, the option to do so would be great in order to produce a documentation from the filtered shape that shows what's really present in the graph.

The issue might be because classes that are still appearing while being counted at 0, are a range in a sh:or syntax for a property counted as > 0,1% .
