Configuring IPv6 listen address falls back to 0.0.0.0

[liamkinne]

When trying to use ::, [::], or even Fly's special fly-local-6pn hostname to configure an IPv6 listen address the logs show starting REST server listening on 0.0.0.0:7280 rest_listen_addr=0.0.0.0:7280.

It does however work by setting the env var QW_LISTEN_ADDRESS to ::. Is the node configuration not being parsed correctly?

Expected behavior
REST server should listen on :: to allow IPv6 connections.
