davidbaumwald 8a8bd9192b Administration: Guard against undefined $GLOBALS['hook_suffix'] in WP_Screen::get().
When initially defaulting the screen `$id` in `WP_Screen::get()`, if the `$hook_name` parameter is not supplied, an `else` fallback uses `$GLOBALS['hook_suffix']`.  However, in some cases, `hook_suffix` doesn't exist in the global scope.  This produces an "Undefined index" notice on < PHP 8, and a warning in >= PHP 8.

This change ensures `$GLOBALS['hook_suffix']` has a value before using it as a fallback for the screen ID.
