theme(fix): social follow/share using new config (#821)

A recent commit changed the config for social to use a map instead of a
list, this broke the social share/follow, though a quick fix seems to
restore it and removes the need for sorting.

Closes #808

I checked the wikipedia example from the original issue and it seems
like this will also fix that. I'm not sure if you had anything else to
fix, feel free to push to my branch.
