Subject: [PATCH] Fix for bug #7875: node editor creates links to nowhere,
 fixes at least one instance where it happens, when dragging a link onto an
 already taken socket, and the existing link being moved to a hidden socket.
 Couldn't find other cases in testing, so assuming it's fixed unless another
 case pops up.
