Some taxa are duplicated

[LienReyserhove]

The following taxa are duplicated in the taxon core:
9741 ,9813 ,9828 ,10002, 10378 ,11143 ,11158 ,11191 ,11200 ,11646 ,12114 ,12116 ,12117
(due to the presence/lack in the authorship field)

We could filter them out of the taxon core, but the problem is that there could be information linked to these taxa in other extension files. If we remove them, people won't be able to search for taxon information. So for now I would keep them in the checklist, and if I have time, I could check whether or not these duplicated taxa re-occur in the extensions
