    Fix import failure status reporting when all_stores_must_succeed=True

    As described in the referenced bug, if a store fails with
    all_stores_must_succeed=True, we never add that store to the
    failed list, nor remove it from the pending-import list, leaving a
    polling client to wait forever. This fixes that by making the revert
    handler of the import task do that if we are the one that failed.
