Fix:IMP : code fauilure due the updated API in backened (by Telegram itself). By using "client.iter_dialogs()" instead of deprecated "GetAllChatsRequest"....

1. As the "GetAllChatsRequest()" has been deprecated by Telegram.
2. Need to use "client.iter_dialogs()" now for the same purpose of getting the chats.
