placeholderOption must set empty value

[po-ku]

if not set a value attribute then submit a inner tag.

 < return '<option' . $this->html->attributes($options) . '>' . e($display) . '</option>';
 ---
 > return '<option' . $this->html->attributes($options) . ' value="">' . e($display) . '</option>';

This has already been fixed in #63. Run a composer update to get the latest version!
