Calling UPDATE against an fts table in a UTF-16 database inserts
corrupted data into the database.  The UTF-8 data is being inserted
directly.  This appears to happen because sqlite3_ value_text()
destructively coerces a value to UTF-8, and it's never converted back
when updating the table. This works around the problem by rearranging
things so that the update happens before the coercion. (CVS 3596)
