Janusz Kaczmarek 4458ac5764 Bug 11650: multiplicated authorities after link_bibs_to_authorities.pl
Under certain circumstances misc/link_bibs_to_authorities.pl creates
multiple authority with identical heading.

Test plan:
1. Have some (2-3) biblio records with some repeated headings
   Have BiblioAddsAuthorities = allow, AutoCreateAuthorities = generate
   Have no authority records
2. Run misc/link_bibs_to_authorities.pl script
3. You will get multiple authority records -- one for each occurence of a
   heading in biblio record.

4. Apply the patch.
5. Repeat 1-3 (remember to have "fresh" biblios, without $9, and no
   authorities).
6. The problem should be fixed.
