models: fix discrepancy in models and live database.
When generating a new migration, these change kept popping up. I've compared with production and adjusted some of the code and added migrations for the rest.
Production redirect has:
fro character varying(2048) NOT NULL,
"to" character varying(2048) NOT NULL
Production committee has:
en_description text DEFAULT ''::text NOT NULL,
nl_description text DEFAULT ''::text NOT NULL
Production examination has:
test_type public.examination_test_type DEFAULT 'Unknown'::public.examination_test_type NOT NULL,
Production group has:
mailtype public.group_mailtype NOT NULL
Production user has:
locale public.user_locale NOT NULL,
