When a Container is not visible there is no need for it to react to touch
events, thus avoid wrapping it in a touch component.

In addition, simplify the style needed for hiding the component. Moving the view
out of the window boundaries no longer works on RN 0.42 on iOS. Seting the size
to 0 works well on both platforms, but in the future (when we upgrade to RN >=
0.43) we should switch to display: none:
