Bug 12212: fix error that prevented sysprefs.sql from loading

The line for inserting AggressiveMatchOnISBN didn't have the right
number of columns.

Test Plan:
1) Attempt to run the web installer OR try to import the sysprefs.sql
into your db
2) Apply this patch
3) Try again, no errors should be reported this time
