Address custom field values not displaying in Admin UI customer detail

[michaelbromley]

Describe the bug
When there are custom fields on the Address entity, their values are not displayed in the address card or address form on the customer detail page.

However, the data is returned correctly from the API, so the problem lies in the UI code.

To Reproduce
Steps to reproduce the behavior:

1. Define a custom field on Address
2. Update an address to have a value in the custom field
3. View the customer in the admin ui
4. The value is missing

Expected behavior
Should show the value and allow editing

Environment (please complete the following information):

• @vendure/core version: 2.0.3
• Nodejs version: any
• Database (mysql/postgres etc): any
