Rejected logins via external scope validations do not redirect back to client

[DonMartin76]

In the following situation, the authorization server does not redirect back to the original client with a ?error=...&error_description=... type of callback, but rather displays its own error message screen:

• The login with an external IdP (such as SAML2 or OAuth2) succeeds
• The scope call to an external service returns allow_login: false

This should lead to a redirect with ?error=access_denied&error_description=..., but instead an error screen is displayed directly in the Authorization Server.

Fixed in wicked 1.0.0-rc.6.
