rasa documentation supports a single response with both a text type and a button type. This commit creates two chat messages for any entry in the messages array that has both a text and button component.

from https://github.com/RasaHQ/rasa-demo/blob/master/domain.yml

    - text: "How is this conversation going?"
      buttons:
        - title: "👍"
          payload: "/feedback{\"feedback_value\":\"positive\"}"
        - title: "👎"
          payload: "/feedback{\"feedback_value\":\"negative\"}"

Fixes #111

@nicholasbulka Thank you very much for this PR. This is a very welcome contribution. Indeed, we overlooked buttons with included text attributes, when we built this component.

May I suggest some changes:

1. Do image and attachments support the text attribute as well? Perhaps you would like to handle them as well.
2. Stylewise, the originalMessages object is never used again and therefore is not necessary. Further, the whole .map(message: RasaMessage) => ... is overkill if you never return anything. Perhaps a simple for ... loop or .forEach will do.
3. Unfortunately, CircleCI builds are not enabled for forked PRs. We have a few checks in place, that I would encourage you to run locally, which otherwise would fail the build after merging: Flow Type Checking yarn flow and Code Styleing with yarn pretty.

Thanks for the contribution. Let me know if there is anything else I can help you with.

Thanks for the pull request. I will make some of the suggested style changes myself and release a new version.

Hey I considered your feedback and I appreciate the merge. I tried to implement what might be a better PR than what I originally posted. I've been pressed for time with releasing and whatnot, but here's what I ended up with. in

`async parseMessages(RasaMessages: Array) {
const validMessageTypes = ["text", "image", "buttons", "attachment"];

let expandedMessages = [];

RasaMessages.filter((message: RasaMessage) =>
  validMessageTypes.some(type => type in message),
).forEach(function(message){

  if(message.hasOwnProperty("text")) {
    const textMessage = {...message}
    delete textMessage.buttons;
    delete textMessage.image;
    delete textMessage.attachment;

    expandedMessages.push(textMessage);
  }

  if(message.hasOwnProperty("buttons")) {

    const buttonsMessage = {...message}
    delete buttonsMessage.text;
    delete buttonsMessage.image;
    delete buttonsMessage.attachment;

    expandedMessages.push(buttonsMessage);
  }

  if(message.hasOwnProperty("image")) {

    const imageMessage = {...message}
    delete imageMessage.text;
    delete imageMessage.buttons;
    delete imageMessage.attachment;

    expandedMessages.push(imageMessage);
  }

  if(message.hasOwnProperty("attachment")) {

    const attachmentMessage = {...message}
    delete attachmentMessage.text;
    delete attachmentMessage.buttons;
    delete attachmentMessage.image;

    expandedMessages.push(attachmentMessage);
  }
});`
