Bug: Summoning abilities don't activate when reloading a session.

[0zuzu]

When reloading a session (battle), the game only activates summoning abilities like Drought, Intimidate, etc if they meet one of these 3 criteria:

• The battle is a trainer battle.
• It's the first wave of a biome for classic mode standards (1, 11, 21, etc)
• The battle wasn't loaded from the menu

This logic doesn't include all scenarios where summoning abilities should trigger, like going from a single to a double battle or changing biomes in endless where it can happen on nearly any floor.

It's also built on a flaw: When reloading a session, all Pokemon on the field are sent out, including the ones who were supposed to already be there.

To fix this issue, I propose storing the current allied Pokemons on the field when saving a session. Then, when loading it, only activate summoning abilities of the Pokemon who weren't on the field when the session was saved.

This, together with #694 should fix most if not all bugs pertaining to reloading sessions.

Drought and Psychic surge are both activated when switching biomes in endless:

After reloading the fight neither activate:

I have a PR to address this: #694

This bug is mainly centered around summoning abilities being ignored when reloading a session. It's not just about battle tags not being saved in a session. But together with your PR it should solve most if not all problems with loading a session.

Using overrides and starting on a certain wave might make that wave valid for this bug.

Does not activate abilities on reload for waves that end in 6 now after the endless update as part of August's beta merge

-Reloading after reloading on a wave that ends in 1 or 6 will also not apply the ability.
(Might need to be clarified)

#1843 (Convo about this, in that case it might've been this one and a combination of #3482 )

#2313 (Delta Stream not activating on refresh and second slot)
Pokemon in the 2nd Slot don't properly set their ability on reload independently of the wave, when the precious battle was Singles.)
