Trying to get repository working

Hey @benawad, thank you very much for your great tutorial. react-native and code sharing is really crappy nd I have a problem to get your repository working:

```
# terminal 1
cd /tmp
git clone https://github.com/benawad/react-native-web-series.git
cd react-native-web-series/
yarn install
cd packages/app/
wml add ../common node_modules/@wow/common
wml start

# terminal 2
cd /tmp/react-native-web-series/packages/app/
yarn start

# terminal 3
cd /tmp/react-native-web-series/packages/app/
yarn run android
$ yarn run android
yarn run v1.14.0
$ react-native run-android
info JS server already running.

To suppress this warning, remove "buildToolsVersion '28.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

* What went wrong:
A problem occurred configuring project ':app'.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

error Command failed: ./gradlew app:installDebug

```
Ok, now:
```
sed -i'' 's/com.android.tools.build:gradle:3.2.1/com.android.tools.build:gradle:3.3.1/g' android/build.gradle
sed -i'' 's/4.7/4.10.2/g' android/gradle/wrapper/gradle-wrapper.properties
```

Now I get:
```
error: bundling failed: Error: Unable to resolve module `dayjs` from `/tmp/react-native-web-series/packages/app/node_modules/@wow/common/dist/modules/CurrentWorkout.js`: Module `dayjs` does not exist in the Haste module map or in these directories:
/tmp/react-native-web-series/node_modules

This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
1. Clear watchman watches: `watchman watch-del-all`.
2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

How it can work in your video? :)

Reproduce the setup from the issue with yarn, wml, and the three terminal commands. Start by inspecting packages/app/android/build.gradle, android/gradle/wrapper/gradle-wrapper.properties, and packages/app/node_modules/@wow/common/package.json; done means the Android build completes and Metro resolves the common package's dayjs dependency.
