chore: don't fail logout if cookie is not found

[jonas-jonas]

This should deflake the CRDB tests, that sometimes fail on master. From what I can tell, the issue is that the cookie can be removed due to other means, which then results in repeated calls to logout failing. Unfortunately, it's pretty difficult to debug, why the cookie is removed in the first place. I am also unsure, why this only happens on CRDB (pretty consistently on CI).
