fix some issues with friend suggestions on standalone sites with no 'suggestme' volunteers. This wrongly pulled up a site directory suggesting everybody on the site. While a better outcome than finding nobody, this does not fit with our ethical design goals. If there are no friends of friends, we will only suggest those who volunteer to be on the default suggestion list. Also do not attempt to load poco data from dead sites.
