workspaceThumbnail: Don't keep stale clones in list

If a clone gets destroyed before the corresponding MetaWindow is
removed from the workspace, we will still find it in the list of
clones and try to destroy it again. Avoid the resulting warnings
by updating the list of clones immediately when a clone is destroyed.
