Title: fix wrong order of result when using withColumn and select(),

Hi,

This PR fix an issue when using select and withColumn.

Without the PR, withColumn were always firsts in the result

```php
$query->select(array( 'Book.Id', 'MyWithColumn', 'Book.Title')->find()
```

Before :
```php
array(
'MyWithColumn' => 'somedata',
'Book.Id' => XXX,
'Book.Title' => Title
)
```

After :
```php
array(
'Book.Id' => XXX,
'MyWithColumn' => 'somedata',
'Book.Title' => Title
)
```
