As you can't do a graceful switchover after master is gone, then - in a
two-node setup - the simplest thing would be just removing slony from
slave.

select _clusterschema.uninstallnode();
drop schema _clusterschema cascade;

You will have to set up the full replication after fixing the old master
anyhow.
