[FIX] website: form visibility shows ids instead of labels

This commit resolves an issue (arose in [1]) where a select field was
displaying IDs instead of labels.

Steps to reproduce:

- Navigate to edit mode
- Drop a form block.
- Select the form action type "create customer" (CRM app must be
  installed).
- Add a field for "country".
- Add another field and set its visibility to depend on the country
  value.

Issue:
Users are seeing IDs instead of country labels.
