Subject: [PATCH] Properly destroy placed blocks on the end platform

The craftbukkit provided implementation of LevelAccessor,
BlockStateListPopulator, does not support destroyBlock calls, simply
ignoring them.

This causes the destroyBlock calls during the generation of the end
platform to be lost. The patch moves the destroy calls and executes them
on the actual world access.
