Vacuum Hatch update crashes when attempting to set particle visibility on an invalid LuaRendering particle effect

Reproduction:
- place a Vacuum Hatch, in /editor
- deconstruct the vacuum hatch (is inconsistent, I think it happens when you deconstruct a hatch on the same tick as or the tick before the update script runs)

Stacktrace:
Error while running event RenaiTransportation::on_nth_tick(1)
LuaRenderObject API call when LuaRenderObject was invalid.
stack traceback:
[C]: in function 'newindex'
...iTransportation/script/event/on_tick_VacuumHatches.lua:51: in function 'handle_vacuum_hatches'
RenaiTransportation/script/event/on_tick.lua:15: in function <RenaiTransportation/script/event/on_tick.lua:9>

That's a pretty specific crash lol, in theory the render particle is created the same instant that the Vacuum hatch is placed so idk how you're destroying it before it fully registers the build. Regardless it's a pretty easy check to add to at least prevent the crash
