    tdf#139643: added a test, that checks the PDF/UA metadata is set
    
    If we enable support for PDF/UA, then the metadata object must be
    present and the metadata must have the PDF/UA flags set, or else
    the PDF document won't be recognied as having PDF/UA. The added
    test checks for this.
