Avoid setting duplicate List-Unsubscribe headers.

I'm running latest version and I'm experiencing this bug.

We'd recommend creating a new troubleshooting thread from scratch in the first instance, posting the full error and stack trace.

There has been another similar report but it isn't exactly the same as this (a different header) and not related to this bug.

It's clear here, either there has been a change to XF that Devs need to adjust - or there's a bug with XF. At this point, I don't think it's user error.
