[question]: Async functions stay pending when testing in localhost

[bolanos-nava]

The async functions staying pending forever were due to not running OneSignal.init on every refresh.

When I first set up my test app, I got the window.Onesignal already defined as an object error, which I thought was due to running init on every refresh, so I added a function to check if the service worker was installed and if it was, skip the initialization. However, doing so prevented the OneSignal web SDK functions from loading and made window.OneSignal undefined. And the window.OneSignal already defined... error was due to React strict mode making the app render twice.

I think it would be good to add a check in the React SDK to see if window.OneSignal is defined and throw an error or warning if it is not.
