Thank you for taking the time to report this bug and helping to make Ubuntu better.
We're in sync with Debian on the haproxy package so this bug should be reported there. For Ubuntu, managing haproxy with systemd units would presumably be easiest; this could also be contributed to Debian.
Workaround: change /etc/init.d/haproxy as you described. Importance -> Medium since a workaround is available.
