[szymonrybczak]

Summary:

Fixes #2392

If intent-filter with android.intent.action.MAIN and android.intent.category.LAUNCHER was preceded by an intent-filter without action/category getMainActivity function would fail.

Test Plan:

1. Clone the repository and do all the required steps from the Contributing guide
2. Put this snippet inside AndroidManifest.xml

      <intent-filter>
        <action android:name="android.intent.action.VIEW" />
      </intent-filter>

3. Run this command:

node /path/to/react-native-cli/packages/cli/build/bin.js run-android

4. App should launch correctly ✅

Checklist

• Documentation is up to date to reflect these changes.
• Follows commit message convention described in CONTRIBUTING.md
