VE-1101: Do not rely on ve.msg on initialization of aliens
VE-1101: Cleaner fix to this bug. With Christian we found out that first script that depends on ve.init.platform is ve.ce.AlienNode (which is defined in ext.visualEditor.core) and ve.init.platfor is initialized in ext.visualEditor.mediawiki (which wasn't a dependency to it).
