Orientation of back camera preview in landscape mode upside-down on iOS initially (in test app)

[janusw]

Another preview-orientation issue on iOS. In contrast to #19, I only see this in the test app (Camera.MAUI.Test), but not in my custom app using the CameraView.

To reproduce:

1. Open the Camera.MAUI.Test app on an iOS device (in version 1.4.7).
2. Rotate the device into landscape mode.
3. Tap "Go to MVVM Cam".
4. The preview is upside down.

Note:

• The preview in portrait mode is always ok.
• When opening the preview page in portrait, and then rotating to landscape, the preview is also ok.
• I only see this problem in the test app, so it may be a specific problem of how the CameraView is used there.

I believe the problem is related to the AutoStartPreview property:

• In the "MVVM Cam" of the test app (where the preview is autostarted), the problem occurs.
• In the "Fullscreen Cam" of the test app (which needs to be started manually), the problem does not occur.
