Fix for User edit info dialog during rotation

[issue]
1. Go to Settings > System > Multiple users;
2. Edit user info;
3. Take a picture in portrait mode;
4. Turn the device to landscape mode;

Observe selected image is not retained;

[rootcause]
Fragments no longer need to check if the dialog
is showing up during onSaveInstanceState.

[test]
1. Edit user info;
2. Select a picture;
3. Turn the device to landscape mode;
