Code review comment for lp:~gary-lasker/software-center/remember-sort-preference-lp966878

Thanks for this update. I'm happy to merge it, the only downside I see is that once the sort method
was changed it will always stay changed. I.e. never jump back to the "default" of the page. I wonder
if its maybe worthwhile to add this to the view_state we keep? I will merge the branch as it is and
investigate that other option a bit.
