Lergo-487-review-comments : 
1. When I move to "All Questions" and then click on a question to view
and then go back to questions list, instead of being on "All Questions"
, it is now on "My Questions" (i.e. "no memory' for selection).   See
how Guy did it for my reports / my students report. It should be
similar.

2. To add to the table also username who created the question. This
should be added also to the page from when we create create lesson/quiz
and add questions to "all questions (we can also wait with that for
LERGO 151).
