Minecolonies version

latest git version branch 1.11

Expected behavior

• /mc colony delete 1 should delete my colony so I can start a new one

Actual behaviour

• Null pointer exception on line 149 ColonyManager.java It can not get the citizenData and failed to do the rest

Steps to reproduce the problem

1. Create a colony
2. Quit minecraft
3. Type /mc colony delete 1 in the server console
4. Error above
5. Additional bonus bug, I can no longer use a Supply Chest

I can fix the error and submit a patch when deleting a Colony
