No way to fetch a single message

[shanness]

As per the docs :-
https://api.slack.com/methods/channels.history

To retrieve a single message, specify its ts value as latest, set inclusive to true, and dial your count down to 1.

This requires taking a messageID (timestamp) which none of the methods do.

My use case is that I need the message text that a user reacts to.

Here's an impl of it. Tested and working.

Doesn't work with non user messages (i.e. bot messages etc) due to this :-

if (GsonHelper.getStringOrNull(event.get("subtype")) == null) {
       messages.add((SlackMessagePosted) SlackJSONMessageParser.decode(session, event));
}

Not sure of the thinking there.
