Correct Ender Dragon Block.

Browse Source 
In Spigot (and Bukkit) the end exit portal frame and first dragon is generated after Ender Dragon Legacy check.
This check tries to find if in world exist Exit Portal, and if it does not find it, it generates everything from scratch.
So, to trick legacy check, it is enough to place 1 End Portal somewhere in (0.0) chunk, and portal will not be generated.
