    tdf#153255 DOCX import: fix footnote order
    
    Simple unit test for tdf#152203 allowed to create
    bad ordering algorithm by accident without noticing
    the problem, which caused problem for most of the DOCX
    files, where serialization in footnotes.xml doesn't follow
    the order of the footnotes.
    
    Regression from commit 9b39ce0e66acfe812e1d50e530dc2ccdef3e1357
    "tdf#76260 DOCX import: fix slow footnote import".
    
    Follow-up to commit 09ae3c01940bbc25ffde51963683b04e3cb4bb6a
    "tdf#152203 DOCX import: fix mixed footnotes/endnotes".
