BUG (or Feature Request?): Choice item not deselected after opposing Pokemon selects two different moves

[jmynes]

1. Opposing Aerodactyl uses Substitute, which should probably already deselect Choice Band
2. Technically, they could be choice band + substitute for some ungodly reason, but this is exceedingly unlikely
3. Aerodactyl uses a Hidden Power, but the item slot still shows Choice Band

This isn't a bug, we don't automatically change the item for you based on what happens in the battle. We plan to add a smarter set switcher that would change the set in obvious cases like this, but we don't plan to change the set based on damage rolls though (e.g. based on the damage, they have to be choice banded). We don't want to cross the line where Showdex is providing you with game sense info.
