Fix showing the query on the item search error page

Previously, the query wouldn't fill into the search box or page title
if e.g. parsing had failed. Now it does!

I'm not sure why the rescue strategy we previously had here doesn't
work anymore (I'm sure it must've in the past sometime?), but this is
simpler anyway, let's go!
