    fdo#77342: sw: fix copy/paste of footnote cross references
    
    The fix for sequence fields broke the footnote references some more;
    simplify it by handling the footnotes in the same way as the sequence
    fields, and not remapping GetExp fields for which the corresponding
    SetExp field / footnote is missing.
    
    Also, don't do any remapping when the target is a clipboard document, to
    prevent modifying the source document.
