[DESCRIPTION OF PROBLEM]
We are facing old "ghost" or "traces" on Master (IPA02) even after uninstall and remove replicas (ipa03 and ipa04) present in the cluster.
===============================================================

Version-Release number of selected component (if applicable):
   Hostname  : ipa02.example.com
   OS Version: Server 7.8 (Maipo)  <<--Replica

    Hostname  : ipa04.example.com
    OS Version: Server 7.9 (Maipo) <<--Master
===============================================================

[HOW REPRODUCIBLE]
We have removed ipa03 and ipa04 from IPA02 (master) using:
Remove the old replicas from IPA02:
  A- REMOVE THE IPA04
        # ipa-replica-manage del ipa04.example.com --force --cleanup
        # ipa host-del ipa04.example.com
        # ipa server-del ipa04.example.com

  B- REMOVE THE IPA03
       # ipa-replica-manage del ipa03.example.com --force --cleanup
       # ipa host-del ipa03.example.com
       # ipa server-del ipa03.example.com

===============================================================

[STEPS TO REPRODUCE]
   1. Remove hosts from IPA cluster
   2. List replicas using [root@ipa02 ~]# ipa-replica-manage list -v 'ipa02.example.com'
   3. Check the result
===============================================================

[ACTUAL RESULTS]
[root@ipa02 ~]# ipa-replica-manage list -v 'ipa02.example.com'
    ipa03.example.com: replica

[EXPECTED RESULT]
[root@ipa02 ~]# ipa-replica-manage list -v 'ipa02.example.com'
