Related to delete link feature

[TrishalaGhetiya]

Problem:

1. When one person deletes the link and other doesn't know about it and tries to send message, it shows failed to send message try again. This doesn't give a clear message to the user that link is deleted. It can also convey that there might be other issue like network problem or such.
2. If I am opening the same link from the tab that I have deleted, it says waiting for alice to join whereas other person is already joined.

Solution:

1. When one user deletes the link, the chat from the other person should also be deleted giving a message this link is destroyed
2. Instead of sending the message "failed to send message try again", should give some specific message like link is deleted.
