adaptive_cloth: fix: Mesh: split edge: reference is broken

The reference to the edge is broken because adding or deleting an edge
can realloc memory which means all the references are invalid. So just
need to recreate the references after a addition or deletion of an
element.

Would really appreciate a borrow checker to handle such
instances.
