TNL-4002

Previously, we were only showing the "more assessments needed" message
when there were 0 assessments, but we also need to show it when there are
0 < n < must_be_graded_by assessments for the user, to prevent a blank
area on the grade report. We also supress feedback comments from peers in
this case.

Required some refactoring of the base test case

Take care to avoid default behavior of get_workflow_info.

TNL-4060

Scope the submission response to the correct form elements.
