  [iOS] Time picker fails to blur after tapping the page while editing hour/minute text fields

Reviewed by Aditya Keerthi.

When editing hour/minute text fields while a time picker is presented and then tapping any non-
editable content on the page to dismiss the time picker and keyboard, the
`-presentationControllerDidDismiss:` `UIPopoverPresentationControllerDelegate` method never gets
invoked by UIKit. As a result, we end up never sending `-accessoryDone` back to the content view and
blurring the time input, which then gets us into a state where subsequent attempts to focus the time
input fail to show a popover, because the content view is still in a state where it thinks the
popover is still presenting.

To address this, we can instead override `-viewDidDisappear:` and notify the popover controller
delegate if needed, which is (luckily) still invoked in this scenario.
