User outline report displaying dategraded instead of datesubmitted

Previous notes: 1) The change affects these modules, so it is expected to have some user with activity/grades on them: data, forum, glossary, lesson, quiz and scorm 2) The tests will be performed as admin because, right now, due to another issue, teachers DON'T have access to individual user reports at all! Testing steps: 1) Go to the participants page and pick some user having grades in the activities listed above. 2) In the navigation menu, go to the Activity Reports -> Outline report for that user. 3) Annotate all the grading dates shown in that page for the activities above. 4) Go to the gradebook and override those grades or go to the activity and recalculate them 5) Go back to the outline report for that user. 6) TEST: Verify that the dates continue being the same (when the grade was initially created, the ones annotated in step 3) and they haven't been updated to the date when the override has happened (now). Final note: At the time of writing this, I'm not sure if the recalculation of grades (quiz, for example) keeps the original date of the grade or no, so in case recalculating makes step 6 above to fail, but override works I'd consider this passed.
