IO: add PLY export test coverage for loose edges and loose vertices

Browse Source 
The input file contains a partial cube, with two regular faces, two
loose edges and one loose vertex. This checks whether the loose vertex
for example is included into the output when exporting with UVs
(loose verts do not have UVs in Blender, so they should get (0,0) UV
in PLY).
