fix error messages displayed twice with form type "sonata_type_native_collection" or "sonata_type_immutable_array" when "error_bubbling" sets to false

I am targeting this branch, because it's a fix.

Closes #2761

Step To Reproduce

• Add an array property on an entity
• Add Count constraints with min=2
• On the Admin of this entity add Sonata\AdminBundle\Form\Type\CollectionType or Sonata\Form\Type\ImmutableArrayType field targeting this new property.
• Add 'error_bubbling' => false form option on this field
• Go to the creation form of this entity and try to submit.
