New VPN/Delete VPN dialogs disappear in Profile list when rotating device

[Chou95]

General information

1. Android Version: 10
2. Version of the app 0.7.5

Description of the issue

There exist some dialog disappearance after screen rotation. I think that screen rotation shouldn't do damange to the UI state. The re-created UI should be the same as before rotation.

I think it is not hard to save the UI state of these dialogs by saving the return value of dialog.isShowing(). In this way, you can decide whether to re-open these dialogs when the phone rotation and UI recreation occur. This may improve the user experience, do you think so?
