Fix Anonymous Functions in google preset

As per google standards, anonymous functions should not have a space between `function` and its arguments. 

```javascript
function(a, b) // good

function (a, b) // bad
```

Reference: 
[google's style guide](https://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml):
Section `Passing Anonymous Functions`, the example.

Thanks to @charlespwd for catching this.
