These samples are not working with version 3.9.0

[acodallo]

I updated to v 3.9.0 and found 3 issues:

• The ConversationStarter doesn't interrupt the active dialog. I'm using a LUIS root dialog which creates child dialogues depending on the intent.
• stack.Poll(CancellationToken.None) was removed.
• Microsoft.Bot.Builder.Dialogs.ResumptionCookie is marked deprecated. I tried using ConversationReference and got a NullPointerException.

Could you comment on the changes needed to make the code work with v3.9 or provide sample code?

Thanks!

I've created a pull request to address the .net sdk ResumptionCookie/ConversationReference changes: https://github.com/MicrosoftDX/botFramework-proactiveMessages/pull/7
