crashtesting: assert on export of fdo59645-3.odt to docx

    tdf#38778 Fix output of the font in DOC run

    The font information should be output before field declaration.
    Added unit test.

    tdf#38778 DOCX output: no double output of the font info

need to also not double output the complex script font info as well
as the western and ctl info

I misread hAnsi as Asian the last time so thought CJK was already
handled, handle it for real this time
