fix(ios): CAPTURE_APPLICATION_BUSY error when dismissing modal by swipe

[BardRedStar]

Fix a bug with modal presentation style controller dismissing on iOS 13 and above. For now, only for audio capture controller.

Platforms affected

iOS 13 and above.

Motivation and Context

Apple added new feature for modals on iOS 13, they might be dismissed by swipe. Such behavior was not handled, so controller threw CAPTURE_APPLICATION_BUSY, on opening new modal.

closes #152
fixes #151

Description

I added audio capture controller as adaptive controller delegate for itself and implemented the method to handle dismiss event. Then I dismiss the controller correctly, as by tap on the “Done” button.

Testing

I didn’t find any tests for this plugin.
