php 7 symfony bug with array

if you create an object list:

Foo:
   type: object
   properties:
     list:
       type: array
       items:
         $ref: "#/definitions/Bar"
 Bar:
   type: object
   properties:
     name:
       type: string

the generation with param -l php-symfony
will create for "Foo" a method

/**
     * Sets list.
     *
     * @param App\Model\SW\Bar[]|null $list
     *
     * @return $this
     */
    public function setList(Bar $list = null)
    {
        $this->list = $list;

        return $this;
    }

this method setList(Bar $list = null) is wrong for PHP 7 because the argument should be "array" instead of "Bar"

Start with the php-symfony generator entry point selected by -l php-symfony and reproduce the provided Foo/Bar schema. Inspect how the generated setList signature is chosen for array properties. Done means the generated setter accepts an array rather than Bar for the listed object array case.
