Occasionally if a JEXL expression results in no variants being captured (like "QD > 20.0" on filtered variants) the per-sample mapping from samples to eval objects can be empty. This semi-hacky fix prevents null pointer exceptions in setting up the resulting empty table (by jumping straight to it in this case)
