Fatal error when creating a new AddThis Field

[churel]

Hello,

I've try this module for drupal 8 (8.1.8) and when I create a addthis field I've go this fatal error :
Fatal error: Declaration of Drupal\addthis\Plugin\Field\FieldFormatter\AddThisFormatter::viewElements() must be compatible with Drupal\Core\Field\FormatterInterface::viewElements(Drupal\Core\Field\FieldItemListInterface $items, $langcode) in /modules/addthis/src/Plugin/Field/FieldFormatter/AddThisFormatter.php on line 39

It seems that this fork resolved this problem: https://github.com/churel/addthis

The problem is that the signature of FormatterInterface::viewElements function has changed, and now it needs a second parameter ($language).
