Alert presentation positioning issue with new modality presentation in iOS 13

[compilotrc]

The new modality presentations in iOS are causing the JHTAlertController to present the alert in unexpected places on the iPad. Specifically when the iPad is in a split view configuration the alert shows up off screen or nearly so. I've verified that the issue is isolated to the JHTAlertController as the presentation functions normally with a standard UIAlertController. I really love the API and have integrated throughout my app so I hope you can address this soon.
