Bug 11175: (QA follow-up) Account for difference in simple_search return

Thanks to a comment from Andrew, I discovered that the return from
simple_search_compat actually differs depending on if you are using
ElasticSearch or Zebra. The 'results' arrayref contains MARC::Record
objects for ES and raw marc strings if you are using Zebra.  This is
actually already dealt with in the misnamed new_record_from_zebra
function inside C4::Search.. so this patch simply replaces our
MARC::Record instantiation code with a call to that function.
