Fuelwood heater problems

[Frunblumglin]

Issue description:

When placing heat sources such as lava buckets (and in my case the lava crystal from bloodmagic) inside the fuelwood heater, the bucket is consumed.

Steps to reproduce:

1. place a fuelwood heater in the world
2. place a lava bucket or other item that should have non-consumables inside
3. cry from seeing the item vanish

I do remember a ticket like this, can't find it right now.
We released a new version yesterday which contains a lot of bugfixes, it might solve this bug too.
