Fix issues with sticky containers and workspaces

* Attach sticky containers to new workspaces when switching
* Fire the close event *before* we start destroying the workspace to
prevent a crash

Because the sticky container now follows the visible workspace, this
simplifies the rendering and container_at logic.
