Fixes and more tests in remove_nodes function

[rbSparky]

I tested a little more and there are some errors to be fixed, I will fix those here
I missed these in the last PR

I'll also add more tests to make sure all cases are covered

[rbSparky]

needed to add these checks to check bounds

    function find_edges_to_remove(nodes, nodes_to_remove)
        return findall(node_id -> begin
            idx = searchsortedlast(nodes_to_remove, node_id)
            idx >= 1 && idx <= length(nodes_to_remove) && nodes_to_remove[idx] == node_id
        end, nodes)
    end
