Some collection forms are broken since Symfony 3 upgrade

https://integrated-latest.e-activesites.nl/admin/block/new?class=Integrated\Bundle\BlockBundle\Document\Block\ContainerBlock
--> 5 fields fixed, but the first one is not saved

https://integrated-latest.e-activesites.nl/admin/block/new?class=Integrated\Bundle\BlockBundle\Document\Block\FeaturedItemsBlock
--> name and value switched for "Link target"

Already fixed:
https://integrated-latest.e-activesites.nl/admin/block/new?class=Integrated\Bundle\ContentBundle\Document\Block\FacetBlock
--> should contain name and field, now only 1 field
