Damien Arrachequesne 05e1278cfa fix: fix race condition in dynamic namespaces ...

Using an async operation with `io.use()` could lead to the creation of
several instances of a same namespace, each of them overriding the
previous one.

Example:

```js
io.use(async (nsp, auth, next) => {
  await anOperationThatTakesSomeTime();
  next();
});
```
