* Fixing issue 673

When the listObjects is called the region was not being calculated ( because the objectName is null) .
This caused a error on s3 to use the perminently redirected address instead of getting the files, now the region is calculated correctly, the code works as expected

* Fixing issue 673 - change from regitlint
