Fixed UITabBarController had userinteraction enabled during transition

transitioningViewController is either UITabBarController or
UINavigationController. If you enable Motion on a UITabBarController
and tap multiple times on the tabBar item, Motion will restart transition on
each tap unless the transition is over. We fix this by disabling interaction
on UITabBarController while transition is happening.
