    tdf#138741 XLSX export: fix crash in setSkipUnusedFileIds
    
    Changed size of maConvertFileIdToUsedFileId vector to the same as
    maSrcFiles size.
    
    Some external references was not inserted into maRefCells,
    that resulted a smaller maConvertFileIdToUsedFileId as was needed.
    
    This crash was caused by:
