Bug 33946: Do not display link to non-existing bibliographic record

If you use biblio-title.inc on a biblio that does not longer exist, "No title" is shown with a link to catalogue/detail?.pl?biblionumber=

We should at least remove the link.

We could even do better and display "No bibliographic record" if the biblio does not longer exist.

Test plan:
Edit mainpage.pl, add
$template->param( your_bib => Koha::Biblios->find(42) );
Edit intranet-main.tt, add
[% INCLUDE 'biblio-title.inc' biblio=your_bib link = 1 %]

Not hit the main page and see what's hapenning.
If you have a bibliographic record with biblionumber=42, its info will
be displayed.
Remove this record and try again => it's replaced with "No bibliographic record"
without a link
