ipa-replica-manage del should have cleaned things up. You can clear out
old RUVs with ipa-replica-manage too via list-ruv and clean-ruv. You use
list-ruv to get the id# to clean and clean-ruv to do the actual cleaning.

I think we'd need to see ipareplica-install.log to know for sure. It
could be the sort of thing where it fails early but doesn't kill the
install, so the last error is a red herring.
