Remote Schema - Self Referencing Relationships

### Is your proposal related to a problem?

Remote schema joins to the same remote schema
IE: `remote-schema-1` --relationship--> `remote-schema-1`

### Describe the solution you'd like

- Do not filter out the `Source Remote Schema` from `Reference Remote Schema`

### Describe alternatives you've considered

I'm currently accomplishing this by creating multiple entries for each gql api

### If the feature is approved, would you be willing to submit a PR?

I'd love to, but I don't have much experience in the codebase
