WorkspacesView: fix removal of workspaces that are not at the end

Workspaces can removed from any index, and in particular they
will be removed by the WorkspaceTracker if they stop containing
windows at some point. Make sure WorkspacesView is not confused
and destroyes the right Workspace objects.
