Creating RR requires the FQDN to be created explicitly

It seems like with API 3.2 and netdb-client-lib 3.2, creating new resource records conveniently included creating missing FQDNs. With our switch to netdb-client-lib 4.0.514, we found that we need to create the FQDN explicitly, before the RR can be created. As such, (at least) the example scripts dnsvs_cname_create.py and dnsvs_rr_create.py don't work anymore, which I have not verified, but did discuss that publicly in the NETVS Matrix community room (where I was taught the solution).
