    Handle 16-char non-uuid user IDs in payload

    If a user_id just happens to be of 16 character length, this will
    cause the convert_uuid_bytes_to_hex function to improperly return
    a UUID value instead of the user_id string unconverted.

    This patch modifies the payload to indicate whether the ID was in
    fact a UUID and the attempt to convert to bytes was successful.

    This change has effect on more than just user IDs. It also resolves
    potential issues with project IDs, group IDs, IDP IDs, and scope IDs.
