sw: DOCX export: fix exporting of hyperlink inside ruby

The problem is that the hints are iterated in order of start position,
and if there is a hyperlink inside a ruby then its end position will be
reached after the end position of the ruby due to the sort order, which
leads to overlapping XML elements.

So for any given position, first export the end positions, then the
start positions.
