LP1937294: Fix Sample Data Load Predictability Issue

Add "ORDER BY id" to the main queries in the functions used to create
call numbers and copies when loading the sample data.  This change
allows the call numbers and copies to be created in a predictable
manner.

The necessity of this change was revealed by the failure of the
20-hold-targeter.t Perl live test on PostgreSQL 11+.  After this
change, that test passes on newer PostgreSQL versions and continues to
pass on PostgreSQL 10.
