Don't trigger an "off" event to itself when luacontroller turns a port off

I hope this doesn't break anyone's setup.

-- Problem:
-- We need to place the new node first so that when turning
-- off some port, it won't stay on because the rules indicate

-- When turning the output off then, it will however cause feedback
-- so that the luacontroller will receive an "off" event by turning
-- its output off.
-- Solution / Workaround:
-- Remember which output was turned off and ignore next "off" event.
