NRRD file cannot be created without voxel data, so an 1x1x1 array was used as image data. However, when the empty segmentation was loaded then this single-voxel geometry was treated as a valid geometry. Fixed by detecting this special case of a single voxel in the segmentation, and considering the geometry invalid in this case. fixes Slicer#7576
