We currently handle config->state_dir/method/channel_path defaults
after config_parse via if (!config->blah) config->blah = ...; I'd
rather we do it for this too for consistency, but not sure we have
a reliable indicator for determining whether or not config->log_level
is unset (GLogLevelFlags enum doesn't have a 0 value so that would
work, but it's hacky to make such an assumption).

This avoids any hacks so it's worth the trade-off in terms of
consistency so:
