Current implementation is from react router 6 migration.
the navigate() function returned from the useNavigate hook should not be called as part of the rendered component. In this case, we want to trigger it when the user sends or burns their whole token balance. So, call it in a useEffect block when this state change occurs.
Remove use from Etokens screen. Getting screens to render Onboarding if the user has no wallet should be done centrally from App.js in another diff (right now, Home and Receive do it, but other screens do not).
