Page ranges not correct in come cases.

1. The algorithm that determines whether a page range contains
   another one had a bug and in some cases misbehaved.

2. When print is pressed we do a final layout and if nothing
   changes and we have the requeted pages we skip the final
   write. However, in this case we did not update the print
   job with the pages to be printed but we have to since in
   the previous write we did not ask for all selected pages,
   rather for the first one to be shown as a preview. Now if
   we have all pages and nothing changed we update the print
   job pages.
