* Fix api-routes-apollo-server-and-client-auth Example
`client.resetStore()` must be called after SignIn, SignOut actions
Otherwise, even the current basic auth is not working 100% of the time...
For example, as caching occurs here:
```
const { data, loading } = useQuery(ViewerQuery)
```
it sometimes (race conditions!) prevents a user from signing in
the current code base.
