ST_PointOnSurface gives EMPTY for non-empty line input

Description
When passing a line with a single distinct point to ST_PointOnSurface you get an EMPTY back. Granted that we don't support invalid geometries, but it would be much more useful to just return _that_ point instead.
Note the discrepancy:
ST_PointOnSurface('LINESTRING(0 0, 10 0)'::geometry) -> POINT(0 0)
ST_PointOnSurface('LINESTRING(0 0, 0 0)'::geometry) -> POINT EMPTY

This was fixed upstream. Let's keep this ticket open until GEOS-3.3.7 is out.
