Spottedleaf 6bac3c95bf Delay open/close callbacks for chests
The logic for chests may invoke block updates, which may not
be safe to perform. For example, inventory closing due to
player logout (which restricts chunk loading due to being
inside an entity status callback) or during shutdown (which has
chunk loading restrictions due to the chunk system being halted).

This also fixes the recheckOpeners function not firing
the redstone event if the open count changes.
