Fix #29384: Mesh without polygons + Modifier crashes when switching to sculpt mode

Browse Source 
There were some issues with PBVH which prevented working it for meshes without faces.

Discussed with Brecht, for benefits of dynamic-topology-sculpting and so better to
make PBVH survive such things.

Added some extra NULL-pointer checks for this.
