Can't change "unsubscribed" marketing status
There are many cases that we should be able to change to marketing status from unsubscribed to subscribed again:
- user just unsubscribed from a specific newsletter and not ALL of them
- missclicked the status while editing contact details
- customer decides that he wants to receive newsletters again
Hopefully we will be able to a) change the unsubscribe marketing status or b) have multiple unsubscribe statuses that differ from each newsletter list.
