add support for multiple calls to Linking.getInitialURL (#46502)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46502

changelog: [internal]

At the moment, Linking module has undocumented restriction that if you call it twice when Android Activity is not available, it will return with an error.

This is unnecessary and can be handled more sensibly.
