Subject: [PATCH] Do not run close logic for inventories on chunk unload

Still call the event and change the active container though. We
want to avoid close logic because it's possible to load the
chunk through it. This should also be OK from a leak prevention/
state desync POV because the TE is getting unloaded anyways.
