Address of the customer should not be displayed while subscribing for new mailing list

Steps to regenerate:

• Navigate to URL: https://demo-trunk.ofbiz.apache.org/ecomseo/
• Register a new user
• Click on profile
• Navigate to contact lists section

Actual: The address of the customer is displayed in the dropdown while subscribing to new mailing list. If the user tries to subscribe to the mailing list selecting address then "The preferred contact mechanism [Postal Address] was not of the right type for the list [Email Address]." error message is displayed. Please refer attachments: 001, 002

Expected: Since the user cannot subscribe to the mailing list via address, the address of the customer should not be displayed in the dropdown.
