Authentication Flows not executed after Identity Provider Redirect

[cgeorgilakis]

Keycloak provides full functionality for using it both as Service Provider and Identity Brokering.
Our users are mainly from external Identity Providers and we have many Clients with different functionality ( some of them use OTP compulsorily, other being able to deny access etc).

However, a blocking bug exists in authedication flows for external users. After Identity Provider Redirect in an authication flow, Keycloak never returns back to this authedication flow and authedication flow finishes after loggin in Identity Provider. This causes users from external Identity Providers not being able to use configured authedication flow per client.

I want to mention that configure Identity Provider "Post Login Flow" is not acceptable for our case. Client MUST decide about the authedication flow NOT the Identity Provider. Different Clients has different authedication flows. Users from external Identity Providers MUST be able to use these clients.

I have created github issue for this. Could you fix these major bug? Is there a way to overcome it that I miss?
