> In FeatureTransfer, OriginalScoreFeature uses original Query instance preserved in LTRScoringQuery
for the evaluation.
> This query is set in RankQuery#wrap during QueryComponent#process.
> With SolrCloud mode, document searches take two steps: finding top-N document ids, and
filling documents of found ids.
> In this case, FeatureTransformer works in the second step and tries to extract features
with LTRScoringQuery built in QueryComponent#prepare.
> However, because the second step doesn't call QueryComponent#process, the original query
of LTRScoringQuery remains null and this causes NullPointerException while evaluating OriginalScoreFeature.
> We can get the original query from ResultContext which is an argument of DocTransformer#setContext,
thus this problem can solve by using it if LTRScoringQuery doesn't have correct original query.
