issue: ENG-7898
Now that this reducer reduces only setAccessTokenActionType , we can move this logic to native, since web doesn't use this action.

1. Tested that on web CSAT is cleared on logout, and is present when user is logged in
2. Tested that on logout CSAT is set to an empty string on native
3. Tested that on login CSAT is set to a non empty string on native
4. Tested that if setNewSessionActionType with cookieInvalidated is dispatched, then the user is logged out and the CSAT is cleared
