The type of ZNC's config option specifies that a configuration like config.User.paul = null; should be valid, which is useful for clearing/disabling property sets like Users and Networks. However until now the config generator implementation didn't actually cover null values, meaning you'd get an error like error: value is null while a set was expected, at /foo.nix:29:10 This fixes the implementation to correcly allow clearing of property sets.
