Wrong app context view names for screen load transactions

### Platform

iOS

### Environment

Develop, TestFlight

### Installed

Manually

### Version

8.25.2

### Did it work on previous versions?

Maybe

### Steps to Reproduce

1. Open iOS-Swift sample app
2. Check screen load transaction in Sentry

### Expected Result

The view_names in the app context should match the transaction name.

### Actual Result

The view_names sometimes is `UITabBarController` or something different. Checkout this sample transaction in [Sentry]()

I guess this is because we add the view_names to the transaction in the client

As the SDK captures the transaction on a background thread, the app navigates to a new screen after it captures the auto-generated screen load transaction.
