Fix facesColoredPerFaceFlatShaded rendering, avoid runtime warnings

See merge request !13

These runtime warnings are not helpful, it may be intentional to have
an object that sometimes does not contain entities of a specific kind,
without changing the drawmode when this happens.

```
warning: numIndices is 0 in renderobject: VolumeMeshNodeVertices
warning: numIndices is 0 in renderobject: VolumeMeshNodeFaces
warning: numIndices is 0 in renderobject: VolumeMeshNodeEdges
```
