[Android] Fix the video settings from crashing the app. Was broke in the commit "Removal of my terrible idea" https://code.google.com/p/dolphin-emu/source/detail?r=2897619ddbd3e3aae8427fc503647c65e770d466 Didn't comment out the line for that preference in the XML. This is disabled for now until the UI overlay for the buttons are implemented directly into the Java front-end.
