Login when coming from the "Logged out" page doesn't redirect correctly

[kulmann]

Describe the bug

When I have an expired session in the browser, I need to follow a private link from my desktop client twice for reaching the correct location.

Steps to reproduce

1. Login in to your oCIS instance
2. Close the browser instance and grab a coffee (more than 5 minutes)
3. Follow a private link from your desktop client

Expected behavior

Log in, then reach the location encoded in the private link.

Actual behavior

I see the "logged out"-page (due to https://github.com/owncloud/web/issues/10063 ) and when I follow the login button from there, I get redirected to my personal space afterwards. Or in other words: following the login from the "logged out" page loses the information about the desired location.
