SceneCoordinator - iOS 13 Support

[faris-mobile89]

I noticed the app on iOS 13 has an issue on scene-coordinator because of the new behavior of iOS 13 modal( ‘pull-to-dismiss‘). I think the coordinator is not getting this event to pop the current view from the navigation stack. Below is the error after trying to present VC once the previous VC dismissed by "pull-to-dismiss".

Warning: Attempt to present <XX:ViewController: 0x7f96b955f590> on <XX:ViewController: 0x7f96b9621de0> whose view is not in the window hierarchy!
