Point Separate Node: Revert earlier change to point cloud creation

I'm not quite sure creating the "radius" attribute in here is necessary
when any other attribute can be created later, but without this the
original radius attribute didn't pass to the new point cloud components
properly.

This should be investigated though, because the "radius" attribute
of pointclouds currently exists in some "semi-built-in" space that
doesn't really make sense.
