Subject: [PATCH] unsupported property causes an exception

fix for: https://github.com/discord-net/Discord.Net/issues/1436

`SlowModeInterval` property causes an exception for Announcement Channel feature if it is enabled on discord. Should be checked whether it is specified or not before set to property.
