Prevent overfilled bundles from duplicating items (#9633)

Bundles compute the amount to remove from an item based on the formula
(64 - currentWeight) / itemWeight. An overfilled bundle however, with a
currentWeight of > 64 ends up with a negative removal amount for the
item.

This can cause duplication issues on craftbukkit inventory
implementations as they do currently not gracefully handle negative
removal amounts in their remove methods.
