Description
Description of problem:
Unset host/host group's openscap_proxy_id with missing lookup key parameter will cause the following error.
NoMethodError: undefined method `destroy' for nil:NilClass

How reproducible:
1) Choose a host group with openscap_proxy_id set. Lets say host_group_A
2) Web UI -> Configure -> Smart Class Parameters -> search for "server" parameter.
3) In server parameter -> Under "Specify matchers" -> remove host_group_A
4) Web UI -> Configure -> Edit host_group_A -> Unset openscap_proxy_id -> Click submit
Oops, we're sorry but something went wrong undefined method `destroy' for nil:NilClass
