Support OrderBy / Sort for DocumentRepository findOneBy()

[nottoohigh]

Feature Request

Q	A
New Feature	yes
BC Break	no
Version	Since 2.1

Summary

Unlike findBy, Doctrine\ODM\MongoDB\Repository\DocumentRepository::findOneBy does not currently support $sort as a parameter.

Current

 /**
   * Finds a single document by a set of criteria.
 */
public function findOneBy(array $criteria) : ?object
{
  return $this->getDocumentPersister()->load($criteria);
}

Propose adding support for $sort:

/**
   * Finds a single document by a set of criteria.
*/
public function findOneBy(array $criteria, ?array $sort = null) : ?object
 {
     return $this->getDocumentPersister()->load($criteria, null, [], 0, $sort);
 }
