    AccountWizard: Fix auth error handling. #3155
    
    The problem was that on network error the networkError() and
    finishedWithError() signals both fired. To fix it, I collapse all
    error handing into a slot triggered by finishedWithError().
    
    I tested the redirection case and the invalid credentials case.
