[QA] permanent link from the shares pages shows 'undefined'

[jnweiger]

Describe the bug

The web UI has multiple ways to get a permanent link for a shared file or folder.
Some of them return a useful URL, others return the string undefined

Steps to reproduce

This is reproducable with OCM shares, as well as with local shares.

To demonstrate both, we setup two machines with e.g.

env OCIS_DNSNAME=cat-7rc3-DATE OCIS_VERSION=v7.0.0-rc.3 ./deploy_ocis_bare_metal.sh
env OCIS_DNSNAME=dog-7rc3-DATE OCIS_VERSION=v7.0.0-rc.3 ./deploy_ocis_bare_metal.sh

mutually register the machines in their ocmproviders.json; service ocis restart

Alice at dog invites bob at cat. bob accepts.
Alice shares a folder with local user bob and with the remote user bob.

Both Bobs see the folder in shares -> Shared with me. The folder's 3-dots menu has a 'Copy permanent link' entry. (There is also a chain icon next to the 3-dots menu, that has the same function. When clicked, the text undefined is stored in the clipboard. BAD.

Alice sees the folder in shares -> Shared with others. The folder's 3-dots menu has a 'Copy permanent link' entry. (There is also a chain icon next to the 3-dots menu with the same function). When clicked, the text undefined is stored in the clipboard. BAD.

When a user actually enters the folder, another 3-dots menu appears in the folder's breadcrumbs. When clicking there, a useful URL is stored in the clipboard. OK.

Expected behavior

All 'Copy permanent link' elements copy a permanent link into the clipboard.

Actual behavior

some don't.

Additional context

Javascript Console shows nothing when we get this undefined.
