PHP error on Host Entity Path

When I used a field collection through a reference and try to use the Host Entity Path as a field, it gives a PHP error: "Call to a member function hostEntityId() on a non-object in .../views/field_collection_views_handler_field_host_entity_path.inc on line 32". This is because `$values->item_id` on line 29 is failing, because the relationship changes what gets included in $values.

I solved my own problem (I added the host entity as a separate reference), but this module should also make sure that it gets a valid item_id before attempting to load it as a field collection item.
