iOS: Fix a context menu related crash by removing autorelease from DWMenuItem. Something is stil not quite right here, the popup menu lingering from a long touch on another DWRender and causing the popup to show on a DWRender that doesn't respond to the popup. However the crash was critical and the current misbehavior is not. Also check the pointer passed to dw_menu_popup().
