Registered RNIap.purchaseUpdatedListener is being called before RNIap.requestPurchase resovles.

Expected Behaviour

The promise for RNIap.requestPurchase(productId, false) returns before the event handler registered at RNIap.purchaseUpdatedListener() starts execution

I need this because I am relying on the result of the resolved promise to keep track of feature parameters that I want to associate with the transaction when the purchaseUpdatedListener is called.

// When making a purchase...
const productPurchase = await RNIap.requestPurchase(productId, false)
saveFeatureParamForTransactionID(productPurchase.transactionId, featureParams)

// The purchaseUpdatedListener handler.
function(purchase: InAppPurchase | SubscriptionPurchase) {
    const featureParams = getSavedFeatureParamsForTransactionID(purchase.transactionReceipt)
    await saveRemotelyInBackend(purchase.transactionReceipt, featureParams)
}

Actual behaviour

The purchaseUpdatedListener handler starts execution before RNIap.requestPurchase(productId, false) has returned meaning the getSavedFeatureParamsForTransactionID() function will be called before the featureParams have been saved in saveFeatureParamForTransactionID() meaning the feature params are not retrieved.
