CRAFTBOOK-3435 - Reported by therealsutano

Bukkit API 1.14 now has Chunk.setForceLoaded(true) as a replacement.
-The fix needs to detect when a sign is destroyed and call setForceLoaded(false)
-Another plugin could potentially call setForceLoaded(false), so some way to detect and reverse that is needed. An easy fix might be to call setForceLoaded(true) where the setCancelled is currently called.

This hasn't been the case for a while now
