Bug 37820: Upgrade fails at 23.12.00.023 [Bug 36993]

If table aqbudgets is miissing foreign key
'aqbudgetperiods_ibfk_1' database update fails on
"Can't DROP FOREIGN KEY" error.

To test:
1. Remove changes made in bug 32132, drop foreign key
aqbudgetperiods_ibfk_1 and downgrade your database:
- ALTER TABLE aqbudgets MODIFY COLUMN `budget_period_id` INT(11) NULL;
- UPDATE aqbudgets SET budget_period_id = NULL
WHERE budget_period_id IN(SELECT budget_period_id FROM aqbudgetperiods
WHERE budget_period_description = "Budget for funds without budget");
- DELETE FROM aqbudgetperiods
WHERE budget_period_description = "Budget for funds without budget";
- ALTER TABLE aqbudgets DROP FOREIGN KEY aqbudgetperiods_ibfk_1;
- UPDATE systempreferences SET value="23.1200022" WHERE variable = "Version;
2. Upgrade your database (e.g. running installer/data/mysql/updatedatabase.pl)
=> Update fails on error "Can't DROP FOREIGN KEY `aqbudgetperiods_ibfk_1`;...".
4. Apply this patch.
5. Try to update your database again.
=> Database should now be upgraded succesfully.
=> Confirm table aqbudgets now contains 'aqbudgetperiods_ibfk_1'.
