Subject: [PATCH] Skip collision check if the block is not belong to current
 tick region

A temporary fix of these issues:
https://github.com/PaperMC/Folia/issues/311

Due to that mojang won't ignore the blocks the entity passed by, and sometimes the old position may not be updated and it points to a block that we don't own it, and it will access it during applyEffectsFromBlocks.So the best way to fix that is to skip the collision check of that block because it was already not owned by us and it's not necessary to check it
