Subject: [PATCH 1/2] fix(unet-channels): Invoking .Clear() on two Dictionaries
 within the Shutdown-function

GetConfig() will try to insert new kvp-pairs even though they already exists. Clearing them fixes this and allow, for example, doing StartHost() -> StopHost() -> StartHost() within the same session.
