When adding the stateless SavedStateViewModelFactory constructor in aosp/1859226 it used the AndroidViewModelFactory under the hood, which meant that when using the stateless SavedStateViewModelFactory and creating a ViewModel via CreationExtras, it required an Application to be set.

Having an Application should not be a requirement for creating a ViewModel using the SavedStateViewModelFactory or the AndroidViewModelFactory. We should fix the behavior of the AndroidViewModelFactory to rely on the NewInstanceFactory when no application is available, just like the SavedStateViewModelFactory used to.
