Fix/inconsistent wording downloads report (https://github.com/woocommerce/woocommerce-admin/pull/3844)

* Consistency with wording in Downloads tab

* User Name or username --> used Username consistently
* Ditto for "Order #"
* Only exception: Didn't add "Address" after IP in the table header to save space

* Updated the fixed title as well

* Removed "Title" again after comments
