Make redboxes resilient to react native preloading (facebook#47391)

Summary:
Pull Request resolved: facebook#47391

React Native can preload before the activity is available.

Preloading will execute the js bundle. If the js bundle throws an error, it'll try to render a redbox.

If the activity isn't available, and hasn't been set on the react instance yet, the redbox will just render nothing.

## Changes
In this diff, just re-try displaying the redbox after the application sets the activity on the react instance (i.e: calls onHostResume(activity)).
