Fix term ordering when a vocab only has people and is viewed on the term page.

#6398 

Ok so this was a edge case.  The only way to reproduce this is to have a vocab, that only has "people" in it.  If you name your vocab "people" and give it the path "people" then your terms will not honor sticky without this patch.

The reason is that in all other cases the term page will activate the "person" view and use that, but the "people" in the path tricks the term page into thinking that it is already in the people context.

Although this does fix a bug when calling os_taxonomy_list_attached_entities, I am pretty confident that it only will impact this one site :-)
