Important slack event details missing from 'message' object.

Ref:

botkit/packages/botbuilder-adapter-slack/src/slack_adapter.ts

Line 594 in a02291c

channelData: event.event,

If slack events come as event_callback type then 'authed_users' list is missing from botkit 'message' object.
This is an important information which is missing as we use this list of authed users (for unfurl) to get user details from database.
I think whole payload of slack event should be attached in message object (like in previous botkit versions)

@BhuwanBhaskar ah, hrrm! That field is outside of the main payload.

We should at least copy it into channelData along with the main event.

This will be addressed in the next release -> #1929
