Deadlock with DiscordClient.Dispose().

Created by: Neuheit

Summary

Calling DiscordClient.Dispose() immediately after ready will create a deadlock.

Details

This only occurs when calling Dispose immediately after ready, and works fine when calling it immediately after ConnectAsync or waiting until after ready.

Steps to reproduce

1. Create a discord client and call ConnectAsync()
2. Wait for ready to fire in the same method.
3. Call Dispose().
4. Observe that the rest of the main method is not called.
