Describe the bug

The admin doesn't handle empty labels of list fields very well. The pill under "View" shows the field name, the input when editing is (correctly) empty, and the table header shows "CONTENT-MANAGER.CONTAINERS.LISTPAGE.TABLE-HEADERS.<FIELD_NAME>".

Steps to reproduce the behavior

1. Configure the list view of a collection type (/admin/content-manager/collection-types/<content_type::api::id>/configurations/list)
2. Edit one of the fields, leave the label input empty, and save.
3. Check the value on the pill and the field's table header

Expected behavior

I expect there to be no table header for this field. The pill should probably show the field name and some indication that the label is empty (e.g. <empty> (avatar)
