If the identity dashboard is not registered in Horizon and an admin user logs in they will get a 'Something went wrong' page and are not able to progress further.

    Fix regression when identity panel is not registered.

    When the admin user logs in and the identity dashboard is not
    registered we should simply get the default dashboard instead.
    This fixes a regression introduced in I27300e928855ec10ca5d2a623d636e50d756b698
