Remove db_rewrite_sql() from oaiharvester module

Everywhere in the code db_query() is used as a wrapper around db_rewrite_sql().

Example:

$sql = 'SELECT * FROM {oaiharvester_sets} WHERE set_id = %d';
$result = db_query(db_rewrite_sql($sql), $set_id);
return $set = db_fetch_object($result);

This is not necessary. I now get errors in my log saying:

Unknown column 'n.moderate' in 'where clause' query: SELECT * FROM oaiharvester_harvest_queue WHERE ((n.moderate != 1)) in /home/sites/site23425/web/sites/all/modules/xc/oaiharvester/oaiharvester.module op regel 2323.

Changing $result = db_query(db_rewrite_sql($sql), $set_id); to $result = db_query($sql, $set_id); works.

I replaced every instance of db_rewrite_sql($sql) to $sql and now the errors are gone (and the harvesting is still working).
