Store properties injected by the native app

[Ecarrion]

closes #28

Why

This PR locally stores the BlogIf and token properties that are injected by the native app. This in order to avoid having to pass these properties as parameters through all the react app functions.

How

• Adds AsyncStorage react dependency.

• Adds storeDependency() readDependency() functions to store the properties injected from the native app.

• Update index.tsx to store the injected properties in the local storage.

• Update the jetpackFetch() function to read the blogId and token properties from the local storage.

Testing steps

• Run the app and make sure the shipping list loads correctly (like before).

I'm uncertain if it was an intended change - I think we should decide on using npm or yarn. I think we should keep with yarn to keep the current setup and consistency.

So, what I've noticed, is that npm would change yarn.lock to its coordinates if used. I'd suggest reverting changes from yarn.lock and use yarn add @react-native-async-storage/async-storage --save

Thanks for this @wzieba. My bad, I did npm install ... and didn't think much about it. I'll use yarn from now on.

@Ecarrion which app have you been using to test this change? iOS or Android? I have some difficulties with the Android build and I don't know how to link React Native to the WooCommerce-iOS app.

I think that @react-native-async-storage/async-storage dependency suffers from the same issues as @react-navigation/native does in Android.

#27 tries to address it, but for now, the Android app won't build.

The code looks good! 👍

After merging #27 and adding changes in woocommerce/woocommerce-android#9225 , I was able to successfully run the app and storing credentials works well.

Under the hood, when it comes to Android, values are stored in SQLite database:

I wonder why the authors of async-storage decide to do this, instead of SharedPreferences.
