It turns out that `window.native.someMethod` always evaluates as `undefined` -- even if calling that method would succeed. This change removes checks for such methods so that the WeDo2 blocks can work. Note that the hat blocks are still unimplemented, and some assumptions are made about the form that arguments and `util` will take.
