Think bug in previewing other branches

1. use /_preview_branch/jamestest to load a different branch where the title of one of the lists has changed
2. try and find the list you edited and end up on /results page listing it and other options
3. the title has not changed - bug!
4. click on the list to go to the list page eg /list/GB-COH
5. the title will have changed

view.results() function

Should be:

'all_results': filter_and_score_results(query, use_branch)

I think?

And maybe:

    context['lookups'] = get_lookups(query, use_branch)

Time lost to bug, forgetting about it and rediscovering it again += 25 mins
