Bug: 14064 and Bug: 13643 Fix reordering of rules.

Rules were properly reordered in the backend, and the dom id of
the rules was updated, but the existing links that contained the
rule number was not. This should fix any remaining ordering issues.
Note that this does not need to be merged up to Git master since that
code was already heavily refactored to use rule uids instead of sort
position.
