App hangs if the animation is completed manually with interaction controller enabled.

Hi,

Great library.
Observed an issue with the implementation. The issue is that if an interaction controller and animation controller are both set, and if a transition animation is completed fully by hand after that, the app just hangs.

Reproduction of the bug (Occurs with NavigationController example as well)-

1. In the settings page, choose "Flip" animation type and "Horizontal Swipe" for the "Settings" section
2. Press "Done" (Flip animation observed)
3. Press Settings again (Flip animation observed again)
4. Starting on the right side of the screen, pan to the left side until the "MyView" page is completely visible (so that leaving the mouse/lifting the finger from the touch) does not do any more animation.
5. Now the app hangs.

The problem seems to be that for the animation controller, while the - (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext is called at the beginning of the interaction, since the animation is completed fully manually, the completeTransition method is not called from the [UIView animateKeyframesWithDuration.. ]'s completion handler.

Thanks very much for the detailed bug report. I'll try to reproduce and resolve this issue. :-)

I haven't managed to get to the bottom of this, but have committed a workaround.
