At the moment, when creating a root module, a subscription to the `onError` subject is also created. It captures the scope where `NgModuleRef` is created and prevents it from being garbage collected. Also note that this `NgModuleRef` has a reference to the root module instance (e.g. `AppModule`), which also prevents it from being GC'd.
