setStackRoot causes pop event on iOS

[jmcountryman]

🐛 Bug Report

On iOS, calling setStackRoot causes a pop event to be fired, which does not happen on Android (see videos in "Actual Behavior").

Have you read the Contributing Guidelines on issues?

Yes.

To Reproduce

In the playground app:

1. Comment out or remove this line in LifecycleScreen.tsx
2. Launch the app and choose "Stack".
3. Choose "Push Lifecycle Screen".
4. Choose "Screen popped events".
5. Choose "OK" on the "Screen popped event" modal (this one is expected behavior)
6. Choose "Set Stack Root"
7. On iOS, observe a second "Screen popped event" modal; on Android, observe no "Screen popped event" modal.

Expected Behavior

No pop event is fired, or a pop event is fired on both platforms.

Actual Behavior

A pop event is fired only on iOS.
