When Horizon is not the default theme, and the color palette switcher is used, we were ending up in a broken CSS state because the color definitions were not loaded correctly when calling `/color-scheme-stylesheet/` to get the new stylesheet URLs. The problem was that we were not giving the theme ID to this URL, we were only doing `/color-scheme-stylesheet/:palette_id`, not `/color-scheme-stylesheet/:palette_id/:theme_id`, so the theme color definitions like the ones that define the background color were not loaded. This commit fixes the issue and also changes to recreating the `<link>` tags for the CSS in the head so we can check if they are loaded correctly for easier testing in system specs.
