Automatically close thread when recipient leaves the server

[StephenDaDev]

Is your feature request related to a problem? Please describe.
When a user leaves a server with an open thread, the thread gets a message, but the thread stays open, if you have many threads open it could be a little while before you get to close it, and it has no use since the user is gone.

Describe the solution you'd like
A config option to automatically close a thread when the recipient has left the server.

Who will this benefit
People who have lots of threads and don't wish to keep useless threads open.
