Subject: [PATCH] revert "Better reloading of pending unload chunks"

This change by spigot ensures that many interactins with chunks,
e.g. getting a list of TEs will cause the chunk to be marked for not
unloading and will block their unload. This is especially true for
servers using Timings (it needs to access the TE list of chunks), or
any plugins which need to access entity/TE lists periodically.
