embed: Delay setting initial cluster for YAML

Browse Source 
NewConfig() sets an initial cluster (potentially using a default name)
but we should clear it in the event another discovery option has been
specified.

PR #7517 attempted to address this however it only worked if the name
was left as "default".

(Completely) Fixes #7516
