Fix a bug that it would never run the delete batch requests

There are two problems:
1. `$product_id_map` is an array map with the format like
	 `[ 'online:en:TW:gla_5981' => 5981 ]` while the method
	 `find_delete_product_ids` accepts an array of product IDs.
2. Even though we fix the above issue by using `array_values(
	 $product_id_map)`, WCProductQuery couldn't get the product as well
	 because the product is already trashed.
