    Convert live migration uri back to string

    If live_migration_inbound_addr is set in nova.conf, value of the option
    will be saved under target_connect_addr in migrate_data. Unfortunately,
    the type of value saved in target_connect_addr is unicode, therefore
    when creating URI for live migration over dedicated interface we are
    ending up with unicode type which is not acceptable by libvirt. To fix
    the issue let's convert URI explictly back to string.
