Fixes #1037 by making the edge scores deterministic, this should ensure we always get the same networks regardless of edge ordering.

lgtm!

Actually backing out a litlte bit - isn't this also likely to have clashes because they all have the same score? I.e. it's still sort dependent?

[jthorton]

There should only be a single possible MST with these new edge scores regardless of the graph's ordering though where as the current failures are due to multiple possible MST networks and the returned one is selected based on the ordering of the edges. We also seem to get the same network on main and on the last working commit on gufe so hopefully that shows its not order dependent.

Thanks for the explanation - lgtm.
