Visual studio adding extra spaces on function shorthands

- VSCode Version: 1.3
- OS Version: Ubuntu 16.04
- Language: JS

Steps to Reproduce:

1.Create a simple object with functions shorthand like:

``` js
const x = {
    a(){}
};
```

2.Use VSCode auto format (ctrl+shift+i):

``` js
const x = {
    a(){ } // why vscode add this extra space between braces?
};
```

Any way to disable this?
