Subject: [PATCH] Koenig - Fixed "set on destroyed object" error

refs https://github.com/TryGhost/Ghost/issues/9623
- the `{{koenig-toolbar}} `didReceiveAttrs` hook was triggering an async action when the component was being destroyed so a guard is needed around the call to `set` in the `_hideToolbar` method
