Issue on Input Validators Assignment resolved

[julioMZ]

• Code Style Correction
• Call to the method Symfony\Component\Form\FormFactory#createNamedBuilder instead of Symfony\Component\Form\FormFactory#createBuilder inside the FormFactory#createForm method in order to associate the received name param value as the Form name.
• Change in the access for validators assignment for a field from $fieldConfiguration['validators'] to $fieldConfiguration['validation'] in order to make it compatible with the yml tree structure defined in the Linio\DynamicFormBundle\DependencyInjection\Configuration class and assign the validators properly.
• Changes on Unit Test to make them compatibles with the changes made on the previous point.
