Simplify ActionCable.createWebSocketURL and realphabetize exports (#35810)

* Remove unnecessary variable from ActionCable.createWebSocketURL

* Improve ActionCable test by creating the Consumer before reassigning URL

With this change, the test now actually verifies that the Consumer's url
property changes dynamically (from testURL to `${testURL}foo`).

* Fix alphabetization of ActionCable exports
