PokeCenter's "NO" test doesn't finish the dialog before asserting no healing has happened

[Machinocheese]

Bug Summary

PokeCenter.test.ts seems to have some issues with not going through the cutscene properly.

Steps to Reproduce

Try running some console logs on the test. Example shown below on a combined version of a PokeCenter test:

it("PokeCenter test...", (): void => {
        const { fsp, player, ...extras } = stubBlankGame({
            automaticallyAdvanceMenus: true,
        });
        const firstPokemonInParty: IPokemon = fsp.equations.createPokemon({
            level: 77,
            title: "METAPOD".split(""),
        });
        const nurse = fsp.objectMaker.make<ICharacter>("Nurse", {
            id: "Nurse",
        });
        const machine = fsp.objectMaker.make<IThing>("HealingMachine", {
            id: "HealingMachine",
        });

        fsp.things.add(machine, nurse.right, nurse.top);
        fsp.things.add(nurse, player.right, player.top);

        fsp.itemsHolder.setItem(fsp.storage.names.pokemonInParty, [firstPokemonInParty]);

        fsp.cutscenes.pokeCenter.Welcome();
        console.log("-1: " + fsp.menuGrapher.getActiveMenuName());
        fsp.inputs.keyDownA(player);
        console.log("0: " + fsp.menuGrapher.getActiveMenuName());
        fsp.inputs.keyDownA(player);

        firstPokemonInParty.status = "frozen";

        // Act
        console.log("1: " + fsp.menuGrapher.getActiveMenuName());
        fsp.inputs.keyDownDown(player);
        console.log("2: " + fsp.menuGrapher.getActiveMenuName());
        fsp.inputs.keyDownA(player);
        console.log("3: " + fsp.menuGrapher.getActiveMenuName());

        // Assert
        expect(firstPokemonInParty.status).to.be.equal("frozen");
    });

should produce a console log of something like:
-1: GeneralText 0: Heal/Cancel 1: GeneralText 2: GeneralText 3: GeneralText

The issue with the above is that fsp.inputs.keyDownDown and fsp.inputs.keyDownA are supposed to be called on the Heal/Cancel menu as a means to select the Cancel option, but they instead seem to be acting on a GeneralText menu, which should not respond to fsp.inputs.keyDownDown.

Looks like it's not getting all the way through the cutscene.

Part of the problem is that keyDownDown is an asynchronous call.
