Deeplink on Android fail silently if app is backgrounded and then killed by OS

### Steps to reproduce

1. Clone https://github.com/rajveermalviya/test_deep_links
2. Run the app on Android
3. Gesture/press Android Home button to background the app
4. Run the following command to [emulate](https://developer.android.com/tools/adb#am) Android OS' low-memory killing of background apps

```shell
$ adb shell am kill com.example.test_deep_links
```

5. Trigger a deeplink using the following command:

```shell
$ adb shell 'am start -a android.intent.action.VIEW \
-c android.intent.category.BROWSABLE \
-d "testdeeplinks:///details"'
```

6. Notice that app launches but remains on the Home page, and doesn't route to the Details page.

### Expected results

When the deeplink is triggered, the Details page in the app should be opened.

This can be exercised by skipping the Step 4 and carrying out those steps again. Or clearing the app from Recent apps view (essentially fully terminating it) and then triggering the deeplink with the above command.

### Actual results

When the deeplink is triggered, the Home page in the app is visible and the app doesn't route to the Details page.
