Actualized some reference .dot files

Changes

Updated .dot files which are used as reference graphs in tests

Reason for changes

Real changes in the graph are hard to review when files are not actual

If the reference files are wrong, why are the tests passing?

If the reference files are wrong, why are the tests passing?
References were valid before, but there just were in a obsolete format.

test_get_ip_graph_with_merged_operations just compares node names from loaded graph.

write_dot_graph(merged_ip_graph, str(path_to_dot_file))
load_graph = read_dot_graph(str(path_to_dot_file))
sanitized_loaded_keys = [key.replace('\\n', '\n') for key in load_graph.nodes.keys()]

For this test meta data of node is not important.

Tests for the graphs compares the loaded graph. So the difference in node and edge order is not important.

Maybe we could set up a special function, or a conditional path determined by a boolean argument in the functions, that would only dump the nodes and edges w/o metadata, and rewrite these impacted tests to use these functions instead? No sense in keeping data in reference files which is not checked for anyway.
