Plugin ordering issue with super.method() calls inside an arrow function

[Ryan Murphy]

Issue encountered when running with babel-preset-env when it loads the arrow function transform.

Specifically something like this code where the super call is inside an arrow function.

class Dialog extends SAPDialog {
  fn() {
    setTimeout(() => {
      super.fn();
    }}, 1000);
  }
}

Outputs (where this is wrong):

var D2 = SAPDialog.extend("bchui5.m.D2", {
    fn: function fn() {
        setTimeout(function () {
            SAPDialog.prototype.close.call(this);
        }, 1000);
    }
});

But should be:

var Dialog = SAPDialog.extend("bchui5.m.D2", {
    fn: function fn() {
        var _this = this;
        setTimeout(function () {
            SAPDialog.prototype.close.call(_this);
        }, 1000);
    }
});

Currently the arrow function transform seems to run first.

This is not actually an ordering issue. It was caused by using t.identifier('this') rather than t.thisExpression() so the AST was incorrect for the format expected by the arrow function transform.
