Zettelkasten breaks internal links

I mutated the test case 'Multiple enex files with interEnex links' to use zettelkasten
```json
"isZettelkastenNeeded": true,
"useZettelIdAsFilename": true,
```
[yarle-special-cases.spec.ts.txt](https://github.com/user-attachments/files/16103275/yarle-special-cases.spec.ts.txt)
[test-internotebook_links_A/Table of Contents.md](https://github.com/user-attachments/files/16103282/Table.of.Contents.md)
[test-internotebook_links_B/Table of Contents.md](https://github.com/user-attachments/files/16103286/Table.of.Contents.md)
[test-internotebook_links_B/Note in Notebook B.md](https://github.com/user-attachments/files/16103285/Note.in.Notebook.B.md)

which gives as temporary output (because I commented `afterEach`'s `utils.clearMdNotesDistDir();`)
