Model field (enum via $casts) has type mixed

Description

I have a model where one column is represented as a PHP Enum (string backed enum with currently only one possible option), declared via $casts, but PHPStan reports the type incorrectly as mixed.

Laravel code where the issue was found

enum MyModelType: string
{
    case Foo = 'foo';
}

class MyModel {
    protected $casts = [
        'type' => MyModelType::class,
    ];
}

class Bar {
    function baz(MyModel $m): int
    {
        return match($m->type) {
            MyModelType::Foo => 42,
        };
    }
}

I get now the error message Match expression does not handle remaining value: mixed and when I use \PHPStan\dumpType($m->type) I get Dumped type: mixed instead of the expected MyModelType.

It seems like this only starts happening since I upgraded from 2.3.0 -> 2.3.4 but I'm not 100% sure about that.

This might be fixed with #1494
