> If-Condition to check payload null value in _PayloadScoreQuery.java_ was removed in LUCENE-8038.
Because of that, regarding of the payload value, _payloadsSeen_ is always getting increment.
This has compromised the overall score of the document(for instance, as payloadSeens is always
greater than 0, docScore() in _MinPayloadFunction.java_ only returns payloadScore which can
be zero depending on the payload value). Ideally, it should've returned 1 in case of _payload==null_.
> I have added a simple patch to get started, Please let me know if it needs any improvements. 
> Thanks in advance.
