chore: fix full_bipartite_impl()

[maelle]

👋 @szhorvat! @schochastics and I would need your help to fix full_bipartite_impl(), which might need to happen in the configuration files for Stimulus that are stored in the C library.

The full_bipartite_impl() function has those lines:

rigraph/R/aaa-auto.R

Lines 336 to 338 in 0ef90cc

	if (igraph_opt("add.vertex.names") && is_named(graph)) {
	names(res$types) <- vertex_attr(graph, "name")
	}

That are wrong (no graph exists) but also, I think, useless?

• If they are not useless I suppose I need to edit

  rigraph/src/vendor/cigraph/interfaces/functions.yaml

  Line 212 in 0ef90cc

  DEPS: types ON graph

  to DEPS: types ON res?
• If they are, is the change I made correct? But in that case the change would need to happen in the C repo not here?

Note that I think it is useless because other functions with those lines take graph as an input whereas this function creates a new graph from scratch. So where would names come from?

The same problem exists for biadjacency_impl() (reference to a not existing graph object in the body):

rigraph/R/aaa-auto.R

Lines 2579 to 2581 in 0ef90cc

	if (igraph_opt("add.vertex.names") && is_named(graph)) {
	names(res$types) <- vertex_attr(graph, "name", V(graph))
	}
