fix: Access node owner by top level owner property

[susnux]

• Resolves [Bug]: In version 30, this issue still exists.---Numerical accounts show all files/folders in "Shared" status in the web UI  #47267

Summary

As suggested by @skjnldsv in the previous PR we should not use owner-id directly but just use the top level owner attribute (which will be set to owner-id anyways by default).
This fixes the mentioned issue, moreover I added some tests for the inline status action and a regression test for this bug.

(We nevertheless should fix the wrong type of the owner-id attribute in davResultToNode and cast it to string, but we can do so later in @nextcloud/files)

Happens because Cypress does not compile the sources before testing -> So it fails like it does on master. As soon as we compile it will work here. (No idea why the compile step was removed from cypress?)
