Bug 23593: Link to the bibliographic record from the suggestion (OPAC)

If there is a link between a suggestion and a bibliographic record (ie.
if suggestion.biblionumber is set), it makes sense to have an hyperlink
on the suggestion list at the OPAC.

Test plan:
- Create 2 suggestions
- Create an order from one of them
- Go to the suggestion list at the OPAC
=> The one with the order has a to the bibliographic record
=> The other one is not linked with a bibliographic record, and so the
title is displayed, without hyperlink
