git commit: ffb66b0f4150bb82cbc6a1e7571901fe7724f91e

How reproducible:
always

Steps to Reproduce:
1. Create a CatalogSource that contains the etcdoperator v0.9.2 and v0.9.4
[root@preserve-olm-env data]# cat cs-etcd.yaml 
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: etcd-test
  namespace: openshift-marketplace
spec:
  displayName: Jian Test
  publisher: Jian
  sourceType: grpc
  image: quay.io/olmqe/etcd-index:0.9.2-oc
  updateStrategy:
    registryPoll:
      interval: 10m
[root@preserve-olm-env data]# oc create -f cs-etcd.yaml 
catalogsource.operators.coreos.com/etcd-test created
[root@preserve-olm-env data]# oc get packagemanifest|grep etcd
etcd                                                 Jian Test              3m7s

2. Create the OperatorGroup and subscribe to the etcdoperator 0.9.2 version with Manual approval.
[root@preserve-olm-env data]# cat og.yaml 
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: test-og
  namespace: default
spec:
  targetNamespaces:
  - default
[root@preserve-olm-env data]# oc  create -f og.yaml 
operatorgroup.operators.coreos.com/test-og created


3. Approve the v0.9.2.
[root@preserve-olm-env data]# oc get csv
NAME                  DISPLAY   VERSION   REPLACES   PHASE
etcdoperator.v0.9.2   etcd      0.9.2                Succeeded


4, Update the Upgradable of the OperatorCondition to False.

[root@preserve-olm-env data]# oc get operatorcondition etcdoperator.v0.9.2 -o yaml

    type: Upgradeable


5, Approve the v0.9.4.


Actual results:
The v0.9.4 installed successfully. The operatorcondition  etcdoperator.v0.9.2 was removed.
[root@preserve-olm-env data]# oc get csv
NAME                  DISPLAY   VERSION   REPLACES              PHASE
etcdoperator.v0.9.2   etcd      0.9.2                           Replacing
etcdoperator.v0.9.4   etcd      0.9.4     etcdoperator.v0.9.2   Installing
[root@preserve-olm-env data]# oc get csv
NAME                  DISPLAY   VERSION   REPLACES              PHASE
etcdoperator.v0.9.4   etcd      0.9.4     etcdoperator.v0.9.2   Succeeded


Expected results:
The v0.9.2 should be blocked to v0.9.4.
