Bugfix

Do not fail connection if a client processor initialization fails

What is the current behavior?

If a client processor fails (like HR client if not properly configured), then connection to the dev-server is not initialized properly.

What is the new behavior?

• We are still listening for incoming frames if a client processor initialization fails.
• HR client processor init does not crash if config is invalid.
