Tweak the default SpatialMaterial properties

Roughness is now set to 1 by default and albedo is now white,
even on meshes that do not have any materials defined.

This means there is no longer a visual difference between a
mesh with no materials defined and a mesh with a default
SpatialMaterial defined.
