Removed unnecessary messages when welding

It's back. Hopefully this time without issues. I learned how2git after all.
Again, fixed https://github.com/tgstation/-tg-station/issues/4425
Removed unnecessary "Not enough fuel" messages which are handled by remove_fuel itself and were only triggered when welder is off, creating confusion and chaos.
Lattice was actually deleted even when "welded" with welder that is off, not anymore.
