Coverage for https://bugzilla.redhat.com/show_bug.cgi?id=1774167

1. specify a host parameter with the @ symbol, eg, a package-set, as found in the database:

> echo "select id, name, value, type from parameters" | sudo -u postgres psql -d foreman
could not change directory to "/root"
 id |        name        |        value         |      type      
----+--------------------+----------------------+-----------------
  1 | enable-epel        | false                | CommonParameter
  2 | enable-puppet5     | true                 | CommonParameter
  3 | kt_activation_keys | DEV-RHEL7-INFRA-VIRT | GroupParameter
  4 | kt_activation_keys | DEV-RHEL8-INFRA-VIRT | GroupParameter
  5 | package-set        | @Core                | GroupParameter
  7 | package-set        | @Base                | HostParameter
  8 | package-set        | @Base                | HostParameter
(7 rows)

2. Attempt to upgrade from 6.5 to 6.6
