Display patron messages from OPAC summary page on SCO screen as well.

To test:

- Log in to OPAC and go to patrons 'your summary' page to display note
  and messages
- Apply patch
- Refresh patrons detail page. Verify that it looks the same as before
- Go to SCO
- Log in as such patron
- Verify that note and messages appear the same as on OPAC summary page
