Throw an Error when methodsName is the same as dataName

[everlose]

Following code let {{msg}} output function () { return method.apply(instance, arguments); }.
Here is my code

const app = new Moon({
    el: "#app",
    data: {
        msg: "Hello Moon!"
    },
    methods: {
        msg () {
            this.set('msg', 'Moon Hello');
        }
    }
});

I find there has a method that turn methods.msg to data.msg in src/observer/methods.js .

Ahh yes. I will definitely add a warning for this. This is done so methods can be used in templates like:

<p>{{  someMethod(foo)  }}</p>
