Spottedleaf bfc807c27a Improve spawn loading and debug output for waiting on a chunk (#2595)
Spawn loading has been changed to use getChunkAt calls to manually
load chunks since watchdog can watch these calls and so we guard
against plugins/players changing the radius of a spawn while it's
loading

Debug output has been improved to note the status of the currently
waiting chunk
