Restrict creeating Host Taxon

This restriction needs to be put into place until a proper fix for
the Host Taxon relationship is implemented

The issue is that any Host Taxon uploaded through the WorkBench or
created using the '+' button on the QueryCombobox will always be
created in the current collection.
