Manual tracking does not work when using Intents.

### Step 1: Describe your environment

* Android device: Pixel 3
* Android OS version: Android 9
* Google Play Services version:
* Firebase/Play Services SDK version: 17.2.0

### Step 2: Describe the problem:
While using the ```setCurrentScreen``` method to manually track user engagements, the ```screen_name``` is omitted when using ```Intent``` to move from one ```activity``` to another.

However, if a ```FragmentTransaction``` is executed, the ```screen_name``` tag is logged successfully.

#### Observed Results:

* The ```screen_name``` tag is not logged when using an Intent. However it works as expected when using ```FragmentTransaction```.

#### Expected Results:

* The ```setCurrentScreen``` should log the screen_name as expected for both scenarios.
