Handle default guard config being overwritten by middleware

[bjuppa]

It seems config auth.defaults.guard is set to be the Kontour guard after loggin in to Kontour, so the dashboard displays same as kontour.guard... which is not very useful.

We could remove it from the dashboard, otherwise we'll need to rethink what the auth middleware does.

Is there some way in Laravel of getting original config values from files, or the cache?

[bjuppa]

Nah, there's only one way to get the original values... by require of the actual php config files (done in LoadConfiguration::loadConfigurationFiles() but that is not a way we want to pursue.

I think we should just remove auth.defaults.guard from the dashboard!
