Revert "World: do not refresh ticked chunks list every tick"

Browse Source 
This reverts commit aebcfc516ff97492c58ee478a3944915a777a75e.

this has edge cases in the handling of adjacent chunk locks which I
didn't consider at the time. Once accounting for those edge cases, it
became significantly more complex to the point that I realized this
needed more planning.
