`edgelabel_ranks` gets called for the root graph and all of its cluster subgraphs. It should only double `ED_minlen` for each edge once. Reverting the test for labeled edges to check only the active graph, rather than its root, prevents it from expanding the `minlen` once for every level of cluster containing the edge. Fixes ellson#1246

With the attached file, the lengths of some edges are too long. This occurs in 2.40 but not 2.38. It appears the rank distances are not being set correctly in the cluster. The extra ranks are added to handle the edge labels, but the rank distance is not cut in half. Removing the edge labels, or making them xlabels, or using newrank=true act as workarounds.
