Cascade clone for OneHasMany relationship

[SiViN]

check pls this test...

public function testCloningOneHasManyAuthor()
{
    /** @var Author $author */
    $author = $this->orm->authors->getById(1);

    $booksCount = $author->books->count();
    Assert::same($booksCount, $author->books->count()); //OK

    $newAuthor = clone $author;

    Assert::same($author->name, $newAuthor->name);
    Assert::same($booksCount, $newAuthor->books->count()); //OK
    Assert::same($booksCount, $author->books->count()); //FAIL

    Assert::false($author->isPersisted());
    Assert::true($author->isModified());

    $this->orm->authors->persistAndFlush($newAuthor);

    Assert::true($newAuthor->isPersisted());
    Assert::false($newAuthor->isModified());
    Assert::same($booksCount, $newAuthor->books->countStored());
    Assert::same($booksCount, $author->books->countStored());
}

Here is code + sql command

$author = $this->model->authors->getById(1);
$newAuthor = clone $author;
$this->model->authors->persistAndFlush($newAuthor);

    ::TRANSACTION BEGIN:: 	
    INSERT INTO `authors` (`name`, `born`, `web`, `favorite_author_id`) VALUES ('Writer 1', NULL,         'http://example.com/1', NULL) 	
    UPDATE `books` SET `author_id` = 4 WHERE `id` = 2 	
    UPDATE `books` SET `author_id` = 4, `translator_id` = 4 WHERE `id` = 1 	
    ::TRANSACTION COMMIT::

New author stole books old author..

Ok, I have taken a closer look and this seems to be the wanted behavior and not a bug. By default it does not make sence to duplicate all relationship, this would end with duplicatingn the whole entity tree.

Though, I can image a support by setting a cascade property similarly as for persist/remove. So I'm marking this a feature request.
