revset: fixed sorting issue with spanset

When a spanset was being sorted it didn't take into account it's current
state (ascending or descending) and it reversed itself everytime the reverse
parameter was True.

This is not yet used but it will be as soon as the sort revset is changed to
directly use the structures sort method.
