Describe the bug
phpcbf can not process 'use' keyword correctly when i use mulitiple namespaces seperated by ','.

Code sample

<?php
namespace QL;

use phpQuery,Exception,ReflectionClass;

To reproduce
Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above...
2. Run phpcbf --standard=psr2 --extensions=php test.php
3. Content of test.php became:

<?php
namespace QL;

use phpQuery;

useException,ReflectionClass;

Expected behavior
I hope it would be:

<?php
namespace QL;

use phpQuery;
use Exception;
use ReflectionClass;
