Обсуждение: textsearch-ja - textsearch_senna: Fix a bug that the number of result

Log Message:
-----------
Fix a bug that the number of result was zero when the same senna queries
are used in one SQL command. We need to call sen_records_rewind() when
we reuse cached senna records.

Reported and fixed by Umitanuki.
