[TIMOB-5991] iOS: Kitchensink - Base UI>Tab groups, Animating tab group then rotating device results and switching tabs results in empty tableview

Description: While testing KS, Base UI>Tab groups, I clicked "animate tab group". While it was animated, I rotated the device to landscape and clicked "animate tab group" again. When the tab group returned to its normal state it was smaller than expected on the iPad2 and iPhone 4s. On the iPhone, only a few pixels of the navBar was visible while the tabs were completely off-screen (see attached screenshot). On the iPad, the tabs were visible (see screenshot) and clicking a tab resulted in an empty tableview. Steps to reproduce: 1) Install KS on device 2) Navigate to Base UI>Tab groups while in portrait mode 3) Click "animate tab group" 4) rotate device 5) Click "animate tab group" again 6) If on iPad, click any tab Result: Tab group UI not sized correctly, empty tableviews on tabs Expected: Tab group sized correctly and tableviews populated Note: This also occurs with KS 1.7.5
