Graph view should show edges for notes with self-referencing links

Use case or problem

If a note has a link to itself (for example, a link to a header someplace else in the same note), the graph view is not rendering that link, therefore the graph view is not accurately depicting all associations.

Proposed solution

The graph view should render self-referencing links. If this conflicts with certain writing styles that happen to use a lot of self-referencing links that would be undesired on the graph, then a filter switch could selectively render self-referencing edges.

Current workaround (optional)

There is no workaround. The graph view does not accurately depict all associations.
