DEV: Change the params for categoryNone redirect (#20944)

Makes the params (`router.currentRoute.params`) the same in this codepath as in the regular flow. (issue originally reported in: https://meta.discourse.org/t/category-banners/86241/174)

See also https://github.com/discourse/discourse-category-banners/pull/31 for the first stab at the bug.
