AddressChanged wrote its 301 and re-pointed rules without Problems or the
save-time simulation, and removed only an exact rule whose source equals
the new address literally. It now removes every exact rule that matches
the new address with its options, simulates the 301 and the re-pointing
with the stored rules and writes nothing when that loops, stores an
absolute old address on the site as its path, and skips an address that
is not a path on the site.
