The subscription is directly related to both the log scope and the subscriber. It makes no sense to destroy one of them and keep the subscriptions living. We only had code to destroy subscription with the destruction of log scopes. Add code to destroy subscriptions with destruction of subscribers. Signed-off-by: Leandro Ribeiro <leandrohr@riseup.net>
