webstaff: improve performance of open-ils.search.authority.simple_heading.from_xml
Searching authority.record_entry by comparing are.simple_heading
with the results of authority.simple_normalize_heading() can result
in bad query plans; if we calculate the results of that function
first, we have a much better chance of hitting the index on
simple_heading.
