Overlapping exons prematurely kill C. reinhardtii build

[standage]

Gene GeneID:5716281 in C. reinhardtii prematurely kills an important step in the prepare task. Two issues to address. The first, and pressing, matter is to discard this gene using the typical annotfilter mechanism. The second matter, which will probably have to wait, is the fact that the build continued even though the canon-gff3 step of the grep -v | pmrna --locus | canon-gff3 pipeline failed.
