Registering and Resolving not executed when LifetimeScope parent not found

If a LifetimeScope defines a parent and the parent is not found, neither a exception is thrown nor registering and resolving is executed

LifetimeScope executes in its Awake GetRuntimeParent(), which does throw a VContainerParentTypeReferenceNotFound. However, this exception is silently handled by the Awake's try catch here and added to a waiting list.

The resulting behavior is that, when you run a scene with a LifetimeScope with a parent defined, and the parent is not found, you don't get any error or exception and you don't get neither any registering nor injection
