> [iOS]: View controller not properly unregistered in CDVURLProtocol

> [CDVURLProtocol unregisterViewController:] does not properly unregister the
> Cordova view controller from gRegisteredControllers. The view controller is
> registered in gRegisteredControllers with its "long long" representation, but
> it's unregistered by attempting to remove the view controller object itself
> from the list, which of course is not in the set.
> This causes a crash (EXC_BAD_ACCESS) in my test app (which removes and
> re-creates the view controller through a plugin), because something seems to
> call /!gap_exec again after my view controller has been deallocated. I'm not
> sure if that points to a bigger problem or not. But at any rate, when I
> change [CDVURLProtocol unregisterViewController:] to properly remove the view
> controller from the set, my app never crashes, through multiple recycles of
> the view controller.
> I can attach my sample app, if that's helpful to understanding the crash
> scenario. But the unregister bug is unambiguous, so we could just fix that.
