magento.salesOrderShipment.list with filters does not work

[ecuaryan]

https://github.com/MadisonReed/magentoapi/blob/master/readmes/sales_order_shipment.md --> the list method does not work correctly when filters are provided.

https://github.com/MadisonReed/magentoapi/blame/master/src/resources/sales_order_shipment.js --> we found that if we removed lines 62 - 71 that it fixed the problem

62 modifiers: {
63 filters: function(filters) {
64 // if filters is not an array, wrap it in an array
65 if (!Array.isArray(filters)) {
66 return [ filters ];
67 }
68
69 return filters;
70 }
71 }
