Remove buildWithoutImplicitStatusValues

This was used in DomainInfoFlow to return a DomainResource with no
nameservers without making INACTIVE show up. It was nominally used
in DomainApplicationInfoFlow for the same reason, but that's just
an artifact of the old flow hierarchy since applications never have
INACTIVE set anyways. In either case, now that we have the DomainInfo
return object instead of returning DomainResource directly from the
flow, it's better handled within the flow.
