Issue Description:

Pokemons that only evolve by trade didn't evolve when you trade them with a trainer of the mod

What happens:

i tested using a onix holding metal coat i traded it with a trainer for a clefairy and when he used the onix it did not evolved in a steelix

What you expected to happen:

the pokemons should evolve because they were traded and it would be a easier way of obtaining pokemons that only evolve by trade on single player without having to edit the pokecube files

Steps to reproduce:

1.trade a pokemon with a trainer

Affected Versions (Do not use "latest"):

• Pokecube Core:3.7.3
• Pokecube Revival (if applicable):3.6.2
• Pokecube Mobs (if applicable):2.2.1
• Minecraft: 1.9.4
• Forge:1976

This is currently intentional, as iirc the trainers in the games you can trade with don't usually result in evolution either.
