User notebooks are not editable by admin

[rambalachandran]

Bug description

I installed tljh in Ubuntu 20.04 and created three users

1. admin (created as part of the vm initialization)
2. user1 (created from admin front end)
3. user 2 (created from admin front end) A notebook directory name Projects was created and shared with user1 and user2 as described in https://tljh.jupyter.org/en/latest/howto/content/share-data.html#option-3-create-a-directory-for-users-to-share-notebooks-and-other-files

Expected behaviour

The two expected behaviors are,

1. The notebooks must be visible to admin and users, but its only visible to users. I did a symlink and made it visible using the following command sudo ln -s /srv/Projects /home/jupyter-admin/Projects
2. The notebooks created under this folder by individual users are only editable by users. I expected the notebooks to also be editable by admin users.

Actual behaviour

Notebooks are not editable by admin users. See previous section for more details
