Subject: sms-forward: add workaround to fix removal of messages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removal of messages is broken in RouterOS 7.8:

[admin@MikroTik] > /tool/sms/inbox/remove [ find ]
failure: Interface not running!

Of course the interface is running. Toggling the auto-erase setting
fixes this until next boot. So let's add a workaround...

Reported to support (SUP-110828), but not (yet) acknowledged. 🤨
