bug(rating): There is no directive with "exportAs" set to "index"

[hongbo-miao]

After updating to version 1.0.15, RatingComponent does not work well, which works well before.
The code is like this, very simple:

import { Component } from 'angular2/core';
import { RatingComponent } from 'ng2-bootstrap/components/rating';

@Component({
  selector: 'home-component',
  directives: [RatingComponent],
  template: `
    <rating [(ngModel)]="rate" [max]="max"></rating>
  `
})
export class HomeComponent {
  max: number = 5;
  rate: number = 3;
}

When I load this page, I got error:

EXCEPTION: Error: Uncaught (in promise): Template parse errors:
There is no directive with "exportAs" set to "index" ("a-valuemax]="range.length" [attr.aria-valuenow]="value">
<template ngFor #r [ngForOf]="range" [ERROR ->]#index="index">
({{ index < value ? '*' : ' ' }})
<i (mo"): RatingComponent

This one is related to changes on angular 2.0.0-beta.17 and up. It should be fixed in a newer release. There's a couple of PRs pending #472, #481 (either one will do it) that should fix this issue.

@ciriarte thanks! Just realized this issue is similar too #480
So can be closed together later.
