      As noted in CONTROLLER-2044 and CONTROLLER-2043, we have repeating writerUuid in the journal.

      Perusing akka.persistence, this value is used only for sanity checking in a filter – and that filter will happily live with just empty strings.

      On the write side, write a null String instead of writerUuid.
      On the read side, read the uuid, bump always report empty string.

      This should be a completely ABI compatible change.
