Bug 11784 - fix displaying patron images in self checkout

I suppose this bug was introduced with Bug 10636 (patronimage should
have borrowernumber as PK, not cardnumber)

To test:
- Have a Patron with image. Configure everything to show image in SCO.
- Go to SCO and log in patron
- Image does not show up (broken link)
- Apply patch
- Test with prog, ccsr and bootstrap themes
- Image should display
