sidebar generation does not work as expected when nbs are in folders 3 or more levels deep

[deven-gqc]

Provide a minimally reproducible example

1. start a new project with the nbdev_new template
2. add new notebooks in the nbs folder 3 or more levels deep

This is what a project of mine look like

Upon running nbdev_preview, the sidebar is generated but it created a different section of a nb in the same category

The generated sidebar looks like this,

website:
  sidebar:
    contents:
      - index.ipynb
      - section: exp
        contents:
          - section: camvid
            contents:
              - exp/camvid/4 labels.ipynb
      - section: exp
        contents:
          - section: camvid
            contents:
              - exp/camvid/Untitled0.ipynb
      - section: exp
        contents:
          - section: camvid
            contents:
              - exp/camvid/camvid.ipynb
      - section: exp
        contents:
          - section: camvid
            contents:
              - exp/camvid/skimage save camvid labels.ipynb

It should ideally look like this

website:
  sidebar:
    contents:
      - index.ipynb
      - section: exp
        contents:
          - section: camvid
            contents:
              - exp/camvid/4 labels.ipynb
              - exp/camvid/Untitled0.ipynb
              - exp/camvid/camvid.ipynb
              - exp/camvid/skimage save camvid labels.ipynb

@hamelsmu do you think this is expected behavior or is it a bug?

Seems like a bug - won't have time to look at this for a long time though :/
