Allow native module loads during react instance init

Summary:
## Context
Right now, the ReactInstance construtor eagerly initializes native modules.

## Problem
When these modules initialize, they may load other modules. But, all those loads will fail, because the react instance is in the process of being constructed.

## Changes
Eagerly initialize modules after the react instance is created. That way, these native module requires work.
