Title: don't apply filter 'the_content' to author description

This filter is not applied to the biography in the default themes (at least not in twentyfifteen). Applying it leads to several plugins being displayed twice -- once below the content (as intended), once again below the biography. I observed this problem when trying to display social media buttons.
