[v2.0.0-alpha.7] Found conflicting definitions for... differs from the the definition at

Just testing upgrading to v2, I get this:

```
Found conflicting definitions for \"restaurant_top_tags_args\". The definition at \"query_root.restaurant_top_tags.args\" differs from the the definition at \"query_root.review_tag_sentence.tag.restaurant_taxonomies.restaurant.top_tags.args\".","code":"unexpected"}}
```

The function in question:

```
CREATE
OR REPLACE FUNCTION public.restaurant_top_tags(
_restaurant restaurant,
tag_slugs text,
_tag_types text DEFAULT 'dish' :: text
) RETURNS SETOF restaurant_tag LANGUAGE sql STABLE AS $ function $ WITH tag_slugs_array AS (

UNNEST(string_to_array(tag_slugs, ','))
