Incorrect formatting when destructuring parameters

``` typescript
function drawText({ text = "", location: [x, y] = [0, 0], bold = false }) {  
    // Draw text  
}
```

after formatting document

``` typescript
function drawText( { text = "", location: [x, y]=[0, 0], bold = false }) {  
    // Draw text  
}
```
- whitespaces before and after `=` are removed
- added extra whitespace before `{` in parameters
