The existing EntityPickupItemEvent fixes patch moves the call to LivingEntity#onItemPickup for piglins after the respective EntityPickupItemEvent calls, which is correct. However the patch moved the call so far down the line that the existing logic already mutated the picked up item entity, leading to faulty state being passed to the onItemPickup method. To prevent logic in LivingEntity#onItemPickup to read from an ItemEntity that was already mutated, this commit moves the calls prior to the two respective mutations (either gold_nugget or rest). This was chosen above taking a copy of the original item and restoring state later on to avoid a full item stack clone.
