Fix unclear ban messages

(18:15:09) The Pokemon 'Darkrai' is banned on tier 'XY OU' for the following reasons: Pokemon Darkrai is banned, Dark Pulse, Life Orb. 
Darkrai is the banned thing here, the message makes it kinda clear, but the move/item are unneeeded
(18:15:40) The Pokemon 'Garchomp' is banned on tier 'XY OU' for the following reasons: Double Team, Pokemon Garchomp is banned, Life Orb. 
Here Double Team is banned, but the message is confusing and might make people think Garchomp itself is banned
(18:16:08) The Pokemon 'Garchomp' is banned on tier 'XY OU' for the following reasons: Item Soul Dew, Pokemon Garchomp is banned, Dual Chop.
Same as above, but Soul Dew is banned.
