These series of tests, where we've changed the events to be forwarded to the ConversationList object need to be reworked. You basically need a single test for each, e.g.

it("should pass the call to the conversationList", function() {
  sandbox.stub(tkWorker.conversationList, "conversationOpen");

  handlers['talkilla.conversation-open']( < insert data> );

  sinon.assert.calledOnce(tkWorker.conversationList.conversationOpen);
  sinon.assert.calledWith( <insert data> );
});

Do this for all the ones that get forwarded to the ConversationList object.
