Even if an ibexa_address field is set as optional when creating the content type, Afghanistan ( first item in the drop-down ) is always selected, meaning that the field can never be empty

Steps to reproduce:

1. Create a new content type with an address field that is not required.
2. Create a new content of the new content type and publish it without changes.

Expected result:

The address field should be empty

Actual result:

Afghanistan is selected as country
