Whatever if has label or not, you should render the same way

With form-horizontal and column-size setted, if it has label you render like that

```html
<div class="form-group">
    <label class="col-md-2" ...></label>
    <div class="col-md-10">
        <input .../>
    </div>
</div>
```

If it hasn't label you render like that

```html
<div class="form-group col-md-12">
    <input .../>
</div>
```

And this pull request fix that, always render like the first example
The fixes is some spacing
