Correctly order added annotations when saving or printing

- the annotations must be rendered in the same order as the chronological one.
- fix a bug in document.js which avoids to read a saved pdf correctly in Acrobat:
  there is no need to reset the xref state: it's done in worker.js once everything
  has been saved.
