admin configured instance didn't show up

[MBcom]

I configured an Gitlab instance in admin settings. But in user settings the configured instance did not show up. Did I missed some configuration or must the Gitlab Url contain some special path?

As I have seen the problem is related to the transferred value. The view shows the connect button only if state.url == oauth.instance_url. But under lib/Settings/Personal.php the default value is https://gitlab.com, so the values are different. This should be changed. Maybe it would also be good to allow the configuration of multiple gitlabs at the same time? But this only for the future...
