Missing edges when visualizing Polyhedra with threejs

[jplab]

When visualizing polyhedra with threejs, the edges are missing:

sage: p = polytopes.icosahedron()
sage: p.plot()
Launched html viewer for Graphics3d Object 

but

sage: icosahedron()

seems to have the edges.

During the cleanup while adding mesh plots I overlooked this index that needed to be changed. Oops!
