A host with no local index could remove a remote-only snapshot only by
its plain snapshot ID, which it does not have. snapshot remove passed
its argument through RemoteSnapshotKey, rehashing a remote key so it
never matched. It now resolves the identifier with the same
resolveSnapshotRemoteKey that verify and restore use, so a remote key
or an unambiguous leading part of it works.
