`__hydrate__` action does not work for non-combined producers

[JoelBrd]

local function createPetProducer()
    return Reflex.createProducer({
        cats = { "meow" },
        dogs = {},
    }, {
        addCat = function(state, cat)
            local nextState = table.clone(state)

            local nextStateCats = table.clone(nextState.cats)
            nextState.cats = nextStateCats

            table.insert(nextState.cats, cat)

            return nextState
        end,
        addDog = function(state, dog)
            local nextState = table.clone(state)

            local nextStateDogs = table.clone(nextState.dogs)
            nextState.dogs = nextStateDogs

            table.insert(nextState.dogs, dog)

            return nextState
        end,
    })
end

local function testReflex()
    local petProducer = createPetProducer()
    petProducer.addDog("woof")

    local broadcaster = Reflex.createBroadcaster({
        producers = {
            pets = petProducer,
        },
        dispatch = function(player, actions)
            print("dispatch", player, actions)
        end,
    })
    petProducer:applyMiddleware(broadcaster.middleware)

    broadcaster:start("MockPlayer")

    print("state", petProducer:getState())
end

testReflex()

• Notice that the data for the __hydrate__ action is empty, when the state is evidently non-empty

The issue is getSharedState() : 28 in https://github.com/littensy/reflex/blob/master/src/broadcast/createBroadcaster.lua

• Function assumes a producer that has been created by combineProducers
