arturovt 5a3a154cd8 fix(core): unsubscribe from the onError when the root view is removed (#39940)
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.
