Bug 34182: Don't set biblio.serial based on biblio.seriestitle in AddBiblio

A misunderstanding of the intention of some dead code that probably wanted
to set biblio.series (which doesn't exist) left us setting biblio.serial
if biblio.seriestitle was set. The only thing series and serial have in
common is the first four letters. We shouldn't set serial on something
with a series (unless someone also sets serial on it, of course).

Test plan:
 1. Administration - MARC bibliographic framework - Actions button next to
    Default framework - MARC structure
 2. In the Search for tag input type 942 and click search
 3. Actions button next to 942 - Edit subfields
 4. Tab s - check the checkbox for Editor, uncheck the checkbox for
    Collapsed - Save changes
 5. Cataloging - New record
 6. Click in the input for 000 and hold down Tab until you get past 008
    to fill in mandatory default values, then type any character in 040
    subfield c
 7. Tab 2 - In 245 subfield a type Series not serial
 8. Tab 4 - In 490 subfield a type any character
 9. Tab 9 - Set the value of subfield c to Books
10. Click save and leave the tab open to keep the biblionumber
11. Cataloging - New record - repeat step 6
12. Tab 2 - In 245 subfield a type Serial not series
13. Tab 9 - Set the value of subfield c to Books - Type 1 in subfield s
14. Click save, the biblionumber should be one higher than the first one
15. Reports - Create from SQL
16. Type something in Report name, paste in the SQL
SELECT biblio.serial, biblio.seriestitle, biblio.title FROM biblio WHERE
biblionumber IN ("","")
    and put your first biblionumber in the first "", your second in the
    second.
17. Save report - Run report
18. Series not serial should have a blank in the serial column and the
   character you typed in the seriestitle column; Serial not series
   should have a 1 in the serial column and a blank in the seriestitle
   column.
