Subject: [PATCH] create fallback contextContainer (#37441)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37441

Changelog: [Internal]

i just noticed that `[_delegate createContextContainer]` can be null because it returns `shared_ptr`, we should protect against that!
