UniqueFieldsConstraintValidator class needs dependency injection

Hi @omarlopesino

using these classes will resolve the problem.

use Drupal\Core\DependencyInjection\ContainerFactoryPluginInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;

and in create method add new paramenters

public static function create(ContainerInterface $container, array $configuration, $plugin_id, $plugin_definition) {

Thank you @dineshkumarbollu . Indeed I've already made that solution but forgot to create the MR. Now the MR is created. Please review, thanks!

Committed to latest dev, thanks for the patch.
