"one-to-many" relationship property should be pluralized if configured property name is singular

The "many" side of the relationship doesn't get pluralized correctly. For example, this configuration

"category": {
      "source": "dbo.categories",
      "relationships": {
        "book": {
          "cardinality": "many",
          "target.entity": "book"
        }
      },
      "permissions": [{
        "role": "anonymous",
        "actions": [ "*" ]
        }]
    }

should allow this GraphQL to be executed:

{
	categories {
		items {
			category 
			books {
				items {
					id
					title
				}
			}
		}
	}
}

but instead I have this ("book" instead of "books")

{
	categories {
		items {
			category 
			book {
				items {
					id
					title
				}
			}
		}
	}
}

Start by reproducing the issue with the shown category relationship configuration and GraphQL queries. Done means the configured singular "book" property is exposed as "books" on the many side while the relationship remains queryable as shown.
