LDEV-1138: When the user redos the questions from the learner progress review screen, the answers are populated in the sequence mode, which they weren't before. I think I also corrected an inconsistency in the combined mode which meant that when you redid the questions from the learner review screen and changed the values, if you did redo questions on the "review my answers" screen then you got the answers from the db, rather than from the session.
