#3221: ST_GetFaceGeometry returns NULL for faces with no boundaries

 If you ask for a face having no bounds to ST_GetFaceGeometry, you get a
 NULL back. I'm not sure this is a sane behaviour.

 Strictly speaking, a face with no boundaries would be a topological
 invalidity, so you should maybe get an exception thrown.

 Or, if we want to be "tolerant", we could return a POLYGON EMPTY.

 What do you think, Regina ?
