Closures in Querys no longer possible since 2.0.51-dev

[SusanneWaletzko]

What steps will reproduce the problem?

I have some search models in legacy code that are using closures. Worked fine until update on 2.0.51-dev

What is the expected result?

Search model contains something like

$query = User::find(); 
$dataProvider = new ActiveDataProvider([
            'query' => $query,
        ]);
// confederationId
 if ($this->confederationId) {
         $query->joinWith(['userProfile' => function ($q) {
                $q->andFilterWhere(['user_profiles.confed_id' => $this->confederationId]);
         }]);
 }

expected search query to be extended and search by e.g. "confederationId"

What do you get instead?

Exception
Serialization of 'Closure' is not allowed

    }
 
    /**

    public function __toString()
    {
        return serialize($this);
    }
}

It seems that method \yii\db\Query::__toString() has never been used.
