* Add new global setting to control auto-upload of test reports

* Adds callback to attach a copy of the test report when printing

* Fix for all attachment API endpoints

- The AttachmentMixin must come first!
- User was not being set, as the custom 'perform_create' function was never called

* Remove duplicated UserSerializer

* display uploading user in attachment table

* Add unit test to check the test report is automatically uploaded
