fix(examples): Do not append 'updated via' in restore_alerts example (#147)

Each time you restore alerts "updated via restore_alerts.py" in the
description is appended so you get something like: "${DESCRITPION}
updated via restore_alerts.py updated via restore_alerts.py updated via
restore_alerts.py". This commit removes this part so the description
doesn't grow anymore.
