Use whether react instance is accepting calls to determine whether instance is active

Summary:
There was previously a race condition where hasActiveCatalystInstance would return true, but calling a JS module call on it would result in a crash. Now, hasActivtyCatalystInstance will only return true once the instance is actually accepting calls.

I'll follow this up with a more risky diff that gets rid of hasActiveCatalystInstance and just queues JS calls until runJSBundle is called.
