[BUG] animation.onComplete callback has no param passed to it.

[Moghul]

Expected Behavior

When providing options for a chart, you can set some properties for the animation.

One of the properties is a callback for when the animation is complete. According to the documentation, the callback is passed the same object that the onProgress callback is passed.

Current Behavior

The passed parameter is undefined.

Possible Solution

Haven't looked into fixing it.

Steps to Reproduce (for bugs)

1. Open up Chart.js>samples>animation>progress-bar.html.
2. Add 'console.log(animation);' on line 71.
3. Open the file in a browser
4. See undefined in the console log.

Context

Just something I ran into while trying to get a hold of an instance of the chart.

Environment

• Chart.js version: 2.5.0
• Browser name and version: Any, not browser related.

That's odd given we pass the animation object too it: /~https://github.com/chartjs/Chart.js/blob/master/src/core/core.animation.js#L117
