Fix: False positive geometry randomization in split edges node

See cc7da09c1b.

Splitting edges only potentially affects the order of edges and
vertices. Face corner vertex and edge indices are affected, but their
order isn't affected, and faces aren't affected at all. This didn't
cause problems, but correcting it shows users they can rely on
these consistencies after this operation.
