UniversalEditButton and RenderHash extensions were merged in core, but they're still loaded from CommonSettings.php for UniversalEditButton and secure.php for RenderHash. The result is that there're duplicate <link> for UniversalEditButton and two times ':https=1' in the parser cache hash key at secure.wikimedia.org.
The UniversalEditButton has been disabled on WMF wikis. RenderHash is still active.
Removed RenderHash.
