Bug 30481: Drop unique constraint deleteditemsstocknumberidx

Browse source 
Resolves a sync issue between database and schema caused by
differences between structure and upgrades. Note: newer
databases do not contain this index any longer.

Test plan:
Run dbrev.
Check SHOW CREATE TABLE deleteditems.
Verify that unique index has been dropped, regular index added.
