Description
When using the PhpDocExtractor to extract information about a property, if that property is defined within a trait, the resulting type does not take into consideration the use statements in that trait.

How to reproduce

# src/App/Entity/TestEntity.php

namespace App\Entity;

class TestEntity
{
    use TestTrait;
}

# src/App/Entity/TestTrait.php

namespace App\Entity;

use Doctrine\Common\Collections\Collection;

trait TestTrait
{
    /**
     * @var Collection
     */
    protected $myCollection;
}

$phpDocExtractor = new PhpDocExtractor();
$types = $phpDocExtractor->getTypes(TestEntity::class, 'myCollection');
echo $types[0]->getClassName();

Got: App\Entity\Collection
Expected: Doctrine\Common\Collections\Collection

Additional information

• Tested with other classes as well, not just Doctrine Collection, same result.
• If we add use Doctrine\Common\Collections\Collection; to the TestEntity class, then it works as expected.
• If we add the fully-qualified class name (\Doctrine\Common\Collections\Collection) to the @var tag on the $myCollection property, then it also works as expected.
