    tdf#128148 SwDoc::Append: Copy page descs if any has header/footer
    
    Don't only check the first SwPageDesc, but also its
    follows whether they have a header or footer and copy
    the page styles in this case, since otherwise the
    header/footer content can be wrong if the first page's
    page style doesn't have header/footer but a following
    one does.
