Fixes#9761
Instead of cleaning RecoilState we should keep the api key visible as
long as the user didn't refresh/leave the app, it's better from a UX
perspective and the code is also more elegant, removing a useEffect
Note: the root cause of the bug was a missing "/settings" path in
isMatchingLocation in useCleaningRecoilState (due to the recent
refactoring) ; but I think this fix is better
