port: TeamsInfo.sendMessageToTeamsChannel() doesn't return the correct ConversationReference

[sw-joelmut]

Version

4.15.0

Describe the bug

When calling the TeamsInfo.sendMessageToTeamsChannel method and reply to the new message thread, it replies to the first message sent to the bot instead of the new created one.
DotNet's reference

To Reproduce

Steps to reproduce the behavior:

1. Use the javascript_nodejs/58.teams-start-new-thread-in-channel or typescript_nodejs/58.teams-start-new-thread-in-channel.
2. Replace the use of the teamsCreateConversation method for TeamsInfo.sendMessageToTeamsChannel( ... ).

   this.onMessage( async ( context: TurnContext, next ): Promise<void> => {
      const teamsChannelId = teamsGetChannelId( context.activity );
      const activity = MessageFactory.text( 'This will be the first message in a new thread' ) as Activity;
      const [reference] = await TeamsInfo.sendMessageToTeamsChannel(context, activity, teamsChannelId, process.env.MicrosoftAppId);
   
      await context.adapter.continueConversationAsync(
          process.env.MicrosoftAppId,
          reference,
          async ( t ) => {
              await t.sendActivity( MessageFactory.text( 'This will be the first response to the new thread' ) );
          });
   
      await next();
   });

3. Connect the bot to an MS Teams' channel.
4. Call the bot in the channel conversation with @TeamsStartThreadInChannel.

Expected behavior

Should return the ConversationReference for the new message sent to the Teams' channel.
