Move labman.primer_set 18S and ITS inserts from db_patch_manual.sql into the populate_prod_db.sql

It is not possible to create ITS or 18S primer plates. The example .gif shows an attempt to create an 18S plate; the same error is observed with ITS. 16S and shotgun appear to work.


An observed traceback is below.
