Check_MK Werk 6500: Fixed config generation for shadow hosts/services

ID: 6500 Title: Fixed config generation for shadow hosts/services Component: config Level: 2 Class: Bug fix Version: 1.6.0i1 The Check_MK Micro Core configuration generated by "cmk -U", "cmk -O", or "cmk -R" was broken for shadow hosts/services, leading to CMC crashes later when the core tried to use such a configuration. This was a regression since 1.5.0i1 and has been fixed now.
