Auto-evo miche tree has species that don't exist in the results

[hhyyrylainen]

When working on the food chain tab I noticed that there's an inconsistency in what species it found to be in a patch based on the miche tree and what the auto-evo report showed. Now when adding some workarounds I noticed that the miche tree contains species that aren't in the auto-evo results at all. To me this indicates that there's probably some bug with putting species into the miche tree that shouldn't be in there (all species that are processed by auto-evo should have a result entry for it, so I suspect that maybe some temporarily generated species are accidentally inserted into the miche tree).
