UI: Fix bug where auto-config settings wouldn't apply

The radio buttons had been changed so "Streaming" would be selected by
default, but it only sets the wizard's "type" to streaming if the user
actually clicks the radio button themselves manually, so it would stay
set to "Invalid" by mistake, causing settings to not be applied.
