Further cleanup cfgs in the UI test suite This commit does three things: 1. replaces (the last remaining) never true cfgs by the FALSE cfg 2. fix derive-helper-configured.rs (typo in directive) 3. and comment some current unused #[cfg_attr] (missing revisions) 2024-04-09 23:16:57 +02:00			`#[cfg_attr(all(), empty_helper)]`
