cost_value is not fetched when history contains >= cursor.IN_MAX entries
1. Make > 1000 changes to cost_price on product (with product_cost_history module)
2. Open Products By Location
3. Cost Value is empty for some products
Doing same thing with less cost_price changes, results in correct correct cost_value
I also tried changing cursor.IN_MAX 1000 => 1500, and Products By Location displays cost_values for the same query.
