popupContext ws subscription is added.

Motivation and Context

Fixes the issue Popup chat does not update #1199

Description

When pop-up chat is opened, a new web socket(ws) is created so that the new chat can work properly. When examined, the only difference between normal-chat(chat near video) and popup chat is that, normal chat subscribes a void handler when created, but popup chat does not do that. As a solution, a void handler is created on popup.ts and the web socket subscribed via this handler and popup chat started working.

Steps for Testing

Prerequisites:

• 1 Lecturer

1. Log in
2. Create a course and enable chat
3. Create a lecture and open the chats lecture
4. Open the popup chat and test sendin messages in both chats and check whether both checks are updated accordingly.

Awesome! 🎉 A surprisingly simple fix. I would like to merge and deploy this as soon as possible, so we can use it in the lecture on Wednesday.

I don't really mind the comments.
