TDBQuery.GetWhereClause uses an empty string on a not yet fetched, inserted row. So a numerical cell which is part of a primary/unique key gets into the WHERE clause without any value. Fix that by using "0" as a default if it's an empty string. Avoid usage of UnformatNumber(), which I removed in r4047. Fixes issue #2867.
