Security error while unpacking a received message server replied with a wrong session id telethon

If you send a message from WS to the chat, and then send a message from the chat, then Event is not deleted, if you send another message, it will be processed

Checklist

• [ ] The error is in the library’s code, and not in my own.
• [х] I have searched for this issue before posting it and there isn’t a duplicate.
• [ ] I ran pip install -U https://github.com/LonamiWebs/Telethon/archive/v1.zip and triggered the bug in the latest version.
