Force return type cause TypeError on SingleScalarResult with 1 column

[Zul3s]

Hello,
First, thank for your job.

Second, i want to repport a problem :) .

When i have Doctrine Query with HYDRATE_SINGLE_SCALAR, and this contain only 1 column (ex. count), code have return an Type error because \Steevanb\DoctrineStats\Doctrine\ORM\Event\OverloadedHydratorTrait::hydrateAll need to return an array.

We can see \Doctrine\ORM\Internal\Hydration\AbstractHydrator::hydrateAll doesn't have a PHP return type.
So i think we should juste remove PHP return type on \Steevanb\DoctrineStats\Doctrine\ORM\Event\OverloadedHydratorTrait::hydrateAll.

Exemple of query :

$repository->createQueryBuilder('t') ->select('count(t.id)') ->getQuery() ->getSingleScalarResult();

And error returned :

TypeError: Return value of Doctrine\ORM\Internal\Hydration\SingleScalarHydrator::hydrateAll() must be of the type array, string returned

I didn't see CODE OF CONDUCT, or Test on your projet, can you tell me how can help you to fix this ?

Regards.
