Genetree broken for GRMZM2G059865

[mycrobe]

This is broken currently on dev and, for posterity's sake, the old genetree-vis branch. When this bug is fixed, the first link should show a genetree and the second, being an old, merged feature branch, should not.

The error manifests as an exception caused by a null node here in gramene-trees-client, which is caused by gramene-genetree-vis trying to find the taxonomic distance with a species not in our plant tree (e.g. C. elegans, H. sapiens).

Fixed on dev.
