Redirect not forwarding targetConfigId

[kuruk-mm]

On Alternative Clients we are using targetConfigId parameters, to have a different configuration of the Explorer, for skipping the preview avatar and skipping the lobby. Something that is heavy on Mobile, and we don't require implemented here: #102

We are having issues, that the targetConfigId it's being removed when the website redirects from /auth/requests/{request_id} to the login page, and the targetConfigId it's not working anymore.

I did some commit hunting and I found the following commit introduces that issue: #116

Thanks!
