[FIX] web: utils: patch: restore _super

Before this rev., this._super wasn't correctly reset after being
called. It means that it was sometimes wrongly set, for instance
in the following scenario:

utils.patch(SomeComponent, {
  x: function () {
    this.y();
    this._super(...arguments); // this._super was still y
  },
  y: function () {
    this._super(...arguments);
  },
});

closes odoo/odoo#41691
