Proposal: haveInRepository returns the created entity instead of the primary key

In many tests i have come across situations like this:
```php
$I->haveInRepository(User::class, [
'name' => 'Jane',
'email' => 'jane_doe@gmail.com',
'password' => '123456',
'enabled' => true
]);
$user = $I->grabEntityFromRepository(User::class, [
'email' => 'jane_doe@gmail.com'
]);
// do assertions with the $user
```
Use `haveInRepository`, and then be forced to use `grabEntityFromRepository` to get the entity i just persisted. If i want to check that an entity listener is working, for example, i always have to execute those two statements.

My point is that this would be more useful:
```php
$user = $I->haveInRepository(User::class, [
'name' => 'Jane',
'email' => 'jane_doe@gmail.com',
'password' => '123456',
'enabled' => true
]);
// do assertions with the $user
```
if i wanted to know the primary key of that entity, i would simply write:
```php
$user->getId();
```
In this context, the ORM is useful for its ability to abstract the details of the persistence process and leave it to me as a programmer to worry more about the data i am working with.

I'm not saying that getting the primary key is not useful, i am saying that it is much more useful to get the entity, where there is more information to work with in my tests, including the persistence identifier.

Please let me know your opinions about it.

从 src/Codeception/Module/Doctrine2.php 中链接的 haveInRepository 实现开始，位置大约在第 504-530 行，并将其与 grabEntityFromRepository 进行比较。在决定契约之前，检查现有的返回值行为和相关用法；完成意味着该提案已通过经过测试并记录在案的 haveInRepository 返回值得到解决。
