The error page can't be rendered without the context

Uncaught PHP Exception EasyCorp\Bundle\EasyAdminBundle\Exception\EntityNotFoundException: "The "App\Entity\Order" entity with "orderId = " does not exist in the database.

In production EntityNotFoundException turns from 404 into 500 because the rendering failed here. Pretty annoying because 404s can just be ignored but 500 is something that should probably be looked at.

There's also #5477 which fixes this but this is should be a lot simpler

@simoheinonen thanks for fixing this and sorry it took me so long to fix this.

The error pages still don't fully work for me (I'm trying to find out why), but your PR solves other issues, so let's merge it.
