 If register_taxonomy_for_object_type() is called for an object type which
 is already present in the taxonomy's object_type array, a duplicate value
 is added to the array.

 This is a common occurrence with user-modifiable taxonomy/type definition
 in plugins such as GD Custom Posts and Taxonomies, when:

  * register_taxonomy() is called with object_type argument, based on a
 taxonomy configuration.

  * register_taxonomy_for_object_type() is subsequently called, based on a
 post type configuration.
