Fix middleware function's placements for some `/user/...` (#19377)

- Add reqSignIn to `/user/task/{task}` as it specific to a logged in user currently not-logged in user could cause a NPE.
- Move `/user/stopwatch` & `/user/search` middleware before the actual function is called, because functions are executed in order and currently hadn't any effect and could as well cause a NPE due to that.
- Remove `/user/active` reqSignIn middleware, because when you want to active a account you're not "signed in" so it doesn't make sense to add that middleware.
