mappings/VegCore-VegBIEN.csv: Removed taxonlabel for original taxondetermination, because the original taxondetermination is not scrubbed by scrub.make (only the most current taxondetermination gets scrubbed, because only a single scrubbed determination is added by scrub.make). This still leaves the original taxondetermination's taxonverbatim, which stores the taxonomic information for historical purposes.
