Bug description

Jekyll social is currently not able to handle relative links

How to reproduce the bug

Jekyll social is currently not able to handle relative links. This is already fixed in 0.0.7 of @george-gca , so we should update the dependency :)
Thus, you need to specify a full link in order to ensure al-folio works: https://github.com/dfuchss/fuchss.org/blob/e209d4a3b8dff32d237ad4fbf68886742e247856/_data/socials.yml#L14
