fix type strictness in TokenTrait

[roxblnfk]

Fix

TypeError: strtoupper(): Argument #1 ($string) must be of type string, int given
vendor\cycle\database\src\Query\Traits\TokenTrait.php:175

I'm not sure about that fix because it might be related with building for bad query. After the fix I get some think like this:

---

Upd:

The bad query produces Cycle ORM Scope:

final class UnexpiredTokenScope implements ScopeInterface
{
    public function apply(QueryBuilder $query): void
    {
        $query->andWhere(['@OR' => [
            [Token::F_EXPIRES_AT, '=', new Parameter(null)],
            [Token::F_EXPIRES_AT, '>', new \DateTimeImmutable()],
        ]]);
    }
}

That query code can be replaced with this one:

        $query->andWhere(function (QueryBuilder $query) {
            $query->where(Token::F_EXPIRES_AT, '=', new Parameter(null))
                ->orWhere(Token::F_EXPIRES_AT, '>', new \DateTimeImmutable());
        });

But we need to research if the origin code was correct. If yes - need to fix QueryBuilder
