fix: prevent run-android failure when updating APK (#323)

Summary:
---------

If we run `react-native run-android` while it's already installed, it will fail with the following error.

```bash
info Installing the app on the device (cd android && adb -s emulator-5554 install app/build/outputs/apk/debug/app-x86-debug.apk
adb: failed to install app/build/outputs/apk/debug/app-x86-debug.apk: Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install me.mycake without first uninstalling.]
```

In the development phase, I think using adb's install options below is much more efficient.

```
-r : Reinstall an existing app, keeping its data.
-d : Allow version code downgrade.
```


Test Plan:
----------

Not required.
