Fix T87195: Boolean node multi-input socket only accepts one link
The default insert link callback for nodes was trying to move the
existing link away, since it didn't properly handle multi-input sockets
(though the problem wasn't exposed for the join node). We can basically
skip all of this "moving existing links" for multi-input sockets, unless
we are at the link limit.
