fetchart: Do not emable Wikipedia by default

Because DBpedia seems to be down (it's responding very slowly with errors),
this seems like a good defensive action. It narrows the default sources to
those that resolve quickly, with only a couple of HTTP requests. We can
re-enable this again in the future if things seem to stabilize over at
DBpedia.
