[react-native] Fix Chrome debugging

Summary:
Requiring ExceptionsManager in renderApplication (added in D2023119) led to a transitive require of ExecutionEnvironment, which has to run after InitializeJavaScriptAppEngine.

InitializeJavaScriptAppEngine is the right place for this sort of logic because we control the order that things are loaded, so move the console.error hook initialization there.

Test Plan: Loaded shell app in simulator with Chrome debugging with no errors.
