Fix crash on ReactInstance due to null returned for getViewManagerNames (#52035)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52035

Fixes https://github.com/facebook/react-native/issues/52014

Some OSS library is still returning null for `getViewManagerNames` especially if they're
implementing the `ViewManagerOnDemandReactPackage` in Java.
I'm adding a try-catch here so that we prevent the NPE for those scenarios.
