Description of problem:
When we create catalog source with more than 1 operators, it shows unstable operator number when viewing on Operator Hub Details -> Sources list page

Version-Release number of selected component (if applicable):
4.5.0-0.nightly-2020-04-06-184201

How reproducible:
Always

Steps to Reproduce:
1. create custom catalog source from console(or CLI) using image quay.io/yapei/console-2124:0407
Administration -> Cluster Settings -> Global Configuration -> OperatorHub -> Sources tab -> click 'Create Catalog Source' button ->  set all required fields, set Image (URL of container image) with value quay.io/cajieh/web-console:12.0
2. wait syncing pods running in openshift-marketplace
# oc get catalogsource -n openshift-marketplace
# oc get catalogsource -n openshift-marketplace

3. check which packagemanifest have been synced, we have 3 operator packagemanifests synced which is correct
# oc get packagemanifest | grep 'custom catalog source for console-2124 tetsting'
strimzi-kafka-operator                       custom catalog source for console-2124 tetsting   93m
prometheus                                   custom catalog source for console-2124 tetsting   93m
etcd                                         custom catalog source for console-2124 tetsting   93m                       
4. Check operator number in Operators -> Operator Hub -> Provider Type: Custom
5. Check operator number in Operator Hub Details page, Administration -> Cluster Settings -> Global Configuration -> OperatorHub -> Sources tab

Actual results:
4. In Operator Hub, it shows correct number 3
5. sometimes it shows # of Operators with value 1, sometimes 2, sometimes - 

Expected results:
5. It should show correct operator number in this catalog source, in this case 3
