Subject: [PATCH] Themes: Account for uppercase chars when managing themes.

Fixes a bug where the UI wasn't updated after deleting/updating a theme.

Also introduces unit tests for theme management ajax handlers. For now they're
focused on `wp_ajax_update_theme()` but they can include tests for other
handlers as well.

Props chrisjean for initial patch.
Fixes #37924.
