Route the delivery tests' gorm.Open through gormlog (closes #462)

Six test-only gorm.Open calls in internal/delivery passed a bare gorm.Config, leaving the unfiltered idiom in the tree to be copied into production code, where every gorm.Open goes through gormlog.New. They now pass gormlog.New over a logger that discards, so no gorm.Open in the tree uses a bare gorm.Config. The stale sentence saying the tree has one test-only (*gorm.DB).Scan caller is corrected in the README and in the ParamsFilter comment: only tests call Scan, and what a test binds is fixture data. Test and documentation change only.
