More issues with the battle item refactor

Probably related to:
#2943 #2934

I dont think the first issue can be addressed with tests since you either do an action or you dont. there is no "going back" for tests.
regarding the second I could not find anything that would indicate an issue with the limited info that is given. For tests, hyper potions work in singles aswell as doubles.

Can anyone try to replicate this manually?

Can anyone try to replicate this manually?

Can confirm the Full Restore issue.

EDIT: I don't know about the modern behavior of the item, but in vanilla Pokémon Emerald, the Full Restore is used immediately before choosing the action of the 2nd Pokémon, which is why it makes sense not to be able to go back.

Can't confirm the Hyper Potion one though.

I'm noticing there's an empty space before the Player's name is printed in the potion usage's text string, likely not intentional.

@LOuroboros probably some stuff was fixed with #2940
