The behaviour described above was removed in
812a4b412a, thus henceforth
contradicting `RevertResult`'s xmldoc. As it is relied on by some
external rulesets, bring it back to unbreak them.
Previously, some judgement results were not reverted
when the source DHO is not alive (e.g. frames skipped in editor).
Now, all results are reverted in the exact reverse order.
