Don't assume creator.links contains any data

If $res['name'] is empty (user not found for some reason), there will be no
links.

While the reason I encounter this on my local machine (imported data for which I
don't have the matching users in DB), there may possibly be legitimate ways in
which user name may be missing, IDK.

Either way, if the data is not guaranteed to exist, we should check for it ;)
