Activity. link token in activity confused users

[ScharfViktor]

I found a few problems while increasing the coverage for activity.feature

ocis 6.5.0
web. 10.3.0

1. ## superfluous activities fixed via owncloud/web#11770
Steps:
- admin creates space link (view role by default)
- admin changes link role to edit role
- admin sees activity

Actual:

reason: we send @libre.graph.displayName and type in the PATCH body request if we only update displayName or type(permission)

1.1 ## superfluous activities - #10293
~~Steps: ~~
- admin creates space link with edit role
- public updates file file.txt (public opens file in text editor- put content-> save->close editor)
- admin sees activity

~~Actual: ~~

Expected: file.txt was downloaded via public link fguCwoKHERsDYim is superfluous.

2. link token in activity confused users. I first noticed this when I updated the link password and wondered if I was seeing the password in activity (it was link token)

Steps:

• admin creates 2 space links (Unnamed link and new link)
• admin changes role of the new link
• admin sees activity

Actual: Admin updated permission for a link fhLLZLQKeooTvry on s2
I know that fhLLZLQKeooTvry is link token
But for many users, this may not be obvious

Expected: Admin updated permission for a link new on s2
If we have both Unnamed links -> here is question but maybe better to provide Admin updated permission for a link Unnamed on s2. not sure here

Issue 1 is on us. Issue 2 is more likely a backend issue
