    loginDialog: don't call nonexistent setInitialKeyFocus function
    
    commit ea02380c1524c28e6538ffedb789a12c298742ab changed the login
    dialog to not use ModalDialog anymore.  There's still one lingering
    setInitialKeyFocus method call in the source, which will cause an
    exception to be thrown when users have their user list disabled.
    
    This commit fixes that.
