[MC-47630] Villager Career Crash

When using a custom villager with a career level of 100, if a purchase is made the game crashes. On re-log the item for sale appears in inventory and item used to purchase it is missing from inventory.

What I expected to happen was...:
For transaction to go smoothly with no crashes.

What actually happened was...:
The game crashed

This is not caused by the "CareerLevel" tag, but rather, your "Career" and "Profession" combo. You've provided an invalid combo, where villagers with a profession of 4 only have careers of 0 or 1, while you've inserted 4. When you trade with the villager and exit the GUI, it attempts to update its trades based on its career. Since you're using an invalid career, the game will crash. Use a value of 0 or 1 for "Career" and you won't have issues, and can find the proper values on the wiki: http://minecraft.gamepedia.com/Villager#Professions_and_Careers
