      The ReadPreference::Nearest object constructed by ReshardingOplogFetcher is unused and so ShardRemote::runAggregation() ends up using its default read preference of "secondaryPreferred".

      aggRequest.setUnwrappedReadPref(ReadPreferenceSetting{ReadPreference::Nearest}.toContainingBSON());

      should be set on AggregationRequest constructed in ReshardingOplogFetcher::consume().
