    Test that omitting an optional text parameter from the invocation does not
    leak sentinel values into output renames. The rename template uses
    ${optional_text} which should remain unexpanded (kept as-is) when the
    parameter is not provided, rather than being replaced with a stringified
    NO_REPLACEMENT sentinel.
