v8.0.3 Fixing issues with form_submit payload and submit_once

This release contains 2 small (but for some people important) changes:

• It was not possible to provide a request payload in form_submit as it was always overwritten by the input_values. Now the payload is used when no input_values are provided.
• Fix an issues with submit_once (cannot unpack non-iterable NoneType object)
