This will change the way events are reduced by mixin too ?

In the case I am using a mixin PromiseResolve to resolve each action using a promise to a thunk call.

App:actions:fetch -> PromiseResolve:events:resolve -> App:events:resolve

@Swizz This will change the way events are reduced by mixin too ?

Before the order started with app, now app is last.

With this PR.

const A = () => ({
  events: {
    anyEvent(state, actions, data) {
      console.log(data) //=> Data:
      return data + "A"
    }
  }
})

const B = () => ({
  events: {
    anyEvent(state, actions, data) {
      console.log(data) //=> Data:A
      return data + "B"
    }
  }
})

const C = () => ({
  events: {
    anyEvent(state, actions, data) {
      console.log(data) //=> Data:AB
      return data + "C"
    }
  }
})

const emit = app({
  events: {
    anyEvent(state, actions, data) {
      console.log(data) //=> Data: ABC
    }
  },
  mixins: [A, B, C]
})

emit("anyEvent", "Data: ")
