buySubscription fails with a null pointer exception on Android

See original GitHub issue

Version of react-native-iap

react-native-iap: 1.4.0 react-native: 0.45.1

Platforms you faced the error (IOS or Android or both?)

Android only (iOS works perfectly)

Expected behavior

After succesful initialisation and loading of subscriptions:

RNIap.prepare()
RNIap.getSubscriptions(itemSkus)

Buying a subscription should perform a transaction in play store: RNIap.buySubscription(sku)

Actual behavior

Buying a subscription fails with a runtime exception:

java.lang.NullPointerException: Attempt to invoke virtual method 'int com.android.billingclient.api.BillingClient.launchBillingFlow(android.app.Activity, $
  om.android.billingclient.api.BillingFlowParams)' on a null object reference

@dooboolab good catch!

The component where I initially set up IAP was unmounting and closing the connection. Now it works!

Thanks a lot for your help!
