"Confirmation request" email is sent on customer's newsletter unsubscription

[densen45]

Preconditions

1. PHP 7.0 + 7.1
2. Magento 2.2.4

Steps to reproduce

1. Activate "Need to Confirm" for the newsletter subscription
2. Create a new customer
3. Subscribe to the newsleter
4. Confirm the newsletter subscription (email --> link)
5. Login as the previous created customer
6. Unsubscribe from the newsletter from the customer area

Expected result

1. The customer is being unsubscribed from the newsletter
2. Only the "unsubscription confirmation" email will be sent

Actual result

1. The customer is being unsubscribed from the newsletter
2. The "unsubscription confirmation" email is sent
3. Also the "confirmation request" email is sent although the customer wants to unsubscribe from the newsletter.

This is really odd. The customers are being confused by these "confirmation request" emails. It seems like you don't want them to unsubscribe. The worst thing is that when customers click on the link (because they did not read carefully and assumed they have to confirm the unsubscription) they are being subscribed to the newsletter again.
