Fixer for `Single-line arrays should not have trailing comma.`

PHP does not have a special token-type for the short-array syntax so the only way the look if the `[` relates to a short syntax is to check what came before it.

Its not the best solution but it does work.

```
Symfony\CS\Token Object
        (
            [content] => [
            [id] => 
            [isArray:Symfony\CS\Token:private] => 
            [line] => 
        )
```
