Bug 38112: Restore description of patrons search

Certainly caused by bug 35329.

We used to display a description of the patrons search, but it is no longer displayed.

Test plan:
On the main patrons search select some values in the form on the left
and search. You should see a "Patrons found for: " h3 that will be
displayed and is supposed to describe the current search.
I don't think it's working very well to be honest, maybe a candidate for
candidate, especially if nobody else noticed its disappearance.
