[Bug] Random Trainer Shininess Can End up on the Incorrect Pokémon

Describe the bug

-If a Trainer with a set team randomly has a shiny, the shininess is saved for that slot. If the Trainer is encountered again with changed party slots, then the new Pokémon in that slot will be shiny instead of the previous one.

Seems to consider only consider slot

Expected behavior

The correct Pokémon, if it exists on the player's second encounter with that trainer should be shiny, rather than a different Pokémon.
