In ipa-replica-install we infer that a replication agreement exists if
the host exists. Add an explicit check instead.
What I did to test this was to break out of the installation right after
replication succeeded. Then I'd run ipa-server-install --uninstall and
try the replica install again.

Subject: [PATCH] During replication installation see if an agreement already
We were inferring that an agreement existed if the host was present
as an IPA host. This was not enough if the replica installation failed
