Testing

1. As an admin, go to the BO
2. In the settings, go to decidim_awesome
3. In "Champs de propositions personnalisées", click on "Champs privés" and add a private_field with a condition on a specific process that already have proposals, only on proposals functionality
4. In the application, add 2 or 3 proposals with a response to that private_field
5. Go back to BO, to the list of the proposals of that specific process.
6. Check that when you click on "Répondre à la proposition" for the proposals you have created with private_fields, you can access the proposal's show and you see the private_field
7. Check that when you click on "Répondre à la proposition" for the existing proposals without private_field that you can also access the proposal's show and see that the private_field section is empty.

Testing after answer's import

1. In the BO, on the proposal's list, click on "Importer" and then "Importer des réponses depuis un fichier".
2. Add a CSV or Excel file, with proposal's ids that are not in state "Amendment evaluating", and add answers to them (cf screenshot)
3. Import the answers
4. Check the steps 6 and 7 above, and check that your answers are well imported.
