Breakdown of records by taxonomy bug

Scroll down to the "usage statistics" and view the "Explore by taxonomy" chart. It has an empty kingdom (shows only count) and expanding this node shows the same contents as Animalia node above. User also points out that there is the same problems with other nodes - missing label and the count is not correct (many more child nodes than count suggests) and nodes being shown that are not supposed to be placed in that part of the tree (see ticket).

There is likely a bug in the data that is causing this, as code for the taxon tree has not changed recently.

Won't do before migration to the new infrastructure.
