microBug at connections example

Expected Behaviour

When using the "after" argument at friendsConnection query, the result list should be shifted.

Actual Behavior

The cursor values are shifted, but the result list always starts with the first value.

Minimal graphql.schema and models to reproduce

gqlgen/example/starwars/resolvers.go:

func (r *Resolver) FriendsConnection_edges(ctx context.Context, it *FriendsConnection) ([]FriendsEdge, error) {
	friends, err := r.resolveCharacters(ctx, it.ids)
	if err != nil {
		return nil, err
	}

	edges := make([]FriendsEdge, it.to-it.from)
	for i := range edges {
		edges[i] = FriendsEdge{
			Cursor: encodeCursor(it.from + i),
			Node:   friends[it.from + i],
		}
	}
	return edges, nil
}
