Fixes: #3913#3915
~~You can reproduce the crash by placing a fish bucket on top snow above an unknown node.
I also noticed that the code always uses pointed_thing.above so I fixed that and also added a function to mcl_utils to figure out where a node should be placed (either above or below). Looks like the rest of the code could also use improvement but at least it does not crash now.~~
Cora fixed a bunch of related crashes in Mineclona so I am replacing my commit and cherry picking all her commits here.
