adaptive_cloth: AdaptiveMesh: splittable edges indices set changes

Earlier, an edge wouldn't be tested for if one of it's verts was
already selected (for another edge). This would seems almost correct
but leads to non symmetrical remeshing. So it makes sense to get all
the splittable edges, sort them based on their size and then split the
edge only if it still exists in the mesh.

So changes added:
Give the entire set of splittable edges instead of maximally
independent.
Sort the set based on the edge size.
