Doctrine2 module and option cleanup does not work

I have a functional cest test.
In __before() I create some entities and I assume they will be deleted during __after(), but it does not happen.
I dig a little and found that in `Codeception\Module\Doctrine2` line 174 there is a PDO exception says "There is no active transaction". And when my second test is ran I entities from first test are still exist

从 Codeception\Module\Doctrine2 第 174 行开始，跟踪功能性 Cest 测试如何在 __before() 中创建实体，并在 __after() 中预期进行清理。使用所描述的第二个测试场景重现活动事务异常；当第一个测试中的实体被移除且不出现 PDO 异常时，即表示完成。
