LP#1415572: ensure correct version of authority.normalize_heading() is in place

Some upgraded Evergreen databases can have the wrong version
of the authority.normalize_heading() function in place because
of a mixup in the 0848 schema upgrade script.  The problem can
manifest itself by there being rows in authority.record_entry
where the heading and simple_heading columns have "NOHEADING"
values regardless of the control set:

-[ RECORD 1 ]--+---------------------------------------------
heading | NOHEADING_a ff0ed9fcd13e8944d9a718650840787a
simple_heading | NOHEADING_a ff0ed9fcd13e8944d9a718650840787a

This patch ensures that the correct version is in place and
updates authority.record_entry to fix up affected rows without
requiring a full authority ingest.
