LP#1174359 Need to drop reporter.classic_item_list

ERROR: cannot drop view metabib.full_rec because other objects depend on it
DETAIL: view reporter.classic_item_list depends on view metabib.full_rec
HINT: Use DROP ... CASCADE to drop the dependent objects too.

Beginning at line 55 of the upgrade script, several views and functions are dropped
so metabib.full_rec can be dropped. One of them is missing.

We need to drop reporter.classic_item_list as well, for the script to work.

Add note for the benefit of any Evergreen admin who may
need to recreate that view.  Also, update the point schema
update script.
