Unsubscribe in Sylius should result in unsubscribe in Mailchimp

[loevgaard]

If a customer logs into their account in Sylius and unsubscribe from the newsletter, this change should cascade to Mailchimp obviously

And vice versa

• Add webhook handler: When customer unsubscribe from newsletter at mailchimp side (by clicking unsubscribe link at email)

I guess this has been resolved, as both subscribing and unsubscribing in Sylius are reflected in Mailchimp after a few seconds.
