Comment 9 for bug 1915556

Echoing the rebase. I started to rebase it and submit a collab branch, but I see that the asset.course_module_course_materials has had column revisions in the interim and there might be implications on this patch. Namely column "removal_time" may not be appropriate any longer since I don't see the other related time columns anymore (Creating User, Editing User, Create Time, Edit Time)
