Description: 

To get the entity out of \Drupal\Core\Entity\Plugin\DataType\EntityAdapter, you need to use ->getValue() which is, let's say, not obvious.

#2978067: EntityAdapter should have a getEntity method adds a ->getEntity() method, easing the process.

Before

$this->getParent()->getValue()

After

$this->getParent()->getEntity()
