This PR fixes an issue introduced in
https://github.com/zed-industries/zed/pull/54397 where the Zed Cloud
provider would not be reflected as "authenticated" if a connection to
Collab was attempted, but could not be established.

This was especially noticable when running Zed against a local version
of Cloud and not having Collab running.

This restores the original logic prior to that change.

Release Notes:
