Fixed libbe.storage.util.upgrade

Note that it only upgrades on-disk versions, so you can't use a
non-VCS storage backend whose version isn't your command's current
storage version.  See #bea/110/bd1# for reasoning.  To see the on-disk
storage version, look at
  .be/version
To see your command's supported storage version, look at
  be --full-version

I added test_upgrade.sh to exercise the upgrade mechanism on BE's own
repository.
