Messages are completely disorganized | Not ordered.

Issue Description

I’m attempting to use GiftedChat in the react-native port of our application and we’re running into problems with the order in which messages are displayed, shown in a screenshot below. All of our dates are stored in MIlliseconds since UTC on the Server, porting our messages over looks like so:

var altered = {
                _id: message.key,
                text: message.data,
                createdAt: new Date(message.created_at), // Also tried just message.created_at
                user: {
                    _id: message.sender,
                    name: match.other_user.first_name,
                    avatar: match.other_user.photo
                }
            }

            giftedMessages.push(altered)

The result is this jumbled mess, it doesn’t seem to follow any type of organization. This is a real conversation pulled from our database between two users, one being a test account of ours. We use Firebase, so the timestamp is stored in MIlliseconds since epoch.

Steps to Reproduce / Code Snippets

Just use the example and any dates formed using milliseconds. (IE: Date.now())

Expected Results

Proper ordering of messages.

I really appreciate this library being open sourced, but the fact that there isn’t some sort of default sorting should be advertised on the readme. That is a crucial and integral part of any messaging template. Again, not saying that there needs to be a PR for this, but for the sake of users it would be nice to specify this lack of functionality more clearly upfront.

@qualifyapp GiftedChat will not sort the message for you, it will preserve the order of message as it was in the messages prop Hope that helps
