Editors with save action (AppWrapper) don't use renewed token, 401 on save

[kulmann]

Describe the bug

When I keep an editor open until after a token renewal has happened, attempting to save my work results in a 401. Apparently the renewed token is not being used, but the old expired one.

Steps to reproduce

1. Create an .md file with out text editor app
2. Write some content
3. Wait until you see a token request in the network tab (= token renewal, happens every 5 minutes by default)
4. Click Save in the app top bar

Expected behavior

Document gets saved.

Actual behavior

Document doesn't get saved. I see an error toast, but if I ignore that (and the warning about the dirty state when leaving the page) my work is lost.

Additional context

Needs fixing in current master and in stable-8.0.
@JammingBen and me already looked into this and think that the underlying issue is, that the webdav client gets destructured from the clientService and that the headers loose their reactivity with that.

Tested this with web-7.0.3 on oc10.15.0-rc.1 -- seems unaffected.

? oc10 + web 7 that's not really up 2 date, I don't think it makes sense to put effort into that outdated versions
