Fix T45581: GPU failed to find function node_bsdf_refraction

This commit fixes shader tree compilation, but the shading result wouldn't be
doing actual refraction because it's a bit involved change which isn't really
considered a bug for now. There are more closures which are falling back to
diffuse BSDF currently.
