Well after some time and samba restarts the left over structure elements 
had disappeared.
Had to remove two records with samba-tools because they could not be 
accessed from the MS DNS Snapin.

samba-tool dns delete localhost gsg.local 
"_ldap._tcp.Default-First-Site-Name._sites.DomainDnsZones.gsg.local" SRV 
"server-site1.gsg.local. 389 0 100"
samba-tool dns delete localhost gsg.local 
"_ldap._tcp.Default-First-Site-Name._sites.ForestDnsZones.gsg.local" SRV 
"server-site1.gsg.local. 389 0 100"

Afterwards all appearances of Default-First-Site-Name disappeared.

There remains however still an issue with the site dependant SRV records 
on an server. If a server is moved to another site or an site gets 
renamed. The old SRV records for that server/site remain.
