Mistake in example ChoicesRepository

[karelVanGeerdeghom]

Hello,

In the ChoicesRepository class, in the getChoices method I see this code:

    foreach ($values as $value) {
        $choices[$value->getId()] = $value->getCode();
    }

I had to change this to

    foreach ($values as $value) {
        $choices[$value->getCode()] = $value->getId();
    }

to get it to work.
