Correct location of fire from lightning strikes. Fixes BUKKIT-4707

Previously fires spawned by lightning strikes were in the wrong locations.
This introduced the possibility of having blocks replaced when they should
not be.

EntityLightning now uses the correct locations as defined to spawn the
fires when needed.
