Subject: [PATCH] PaperPR: Fix some beacon event issues
Original license: GPLv3
Original project: https://github.com/PaperMC/Paper
Paper pull request: https://github.com/PaperMC/Paper/pull/9674
Closes Paper#8947
Moves the deactivate event call into the onRemove method for the beacon block itself to prevent it from running when the block entity is unloaded. Also fixes an issue where the events were not being called when the beacon beam gets blocked.
The field I added feels a bit wrong but it works, it's to prevent the activation event being called immediately after loading, can't see any better way to differentiate between a newly placed beacon and a newly loaded one.
