OLM: update to v0.19.1 broke installation

Found on release-1.0 branch during make test_e2e TEST_E2E_FOCUS=olm.API TEST_E2E_ARGS=-ginkgo.failFast:

It works when installing OLM v0.18.3.

There are similar issues on the master branch:

/mnt/workspace/pmem-csi-periodic/_work/bin/operator-sdk run bundle --namespace default --timeout 5m 172.17.0.1:5000/pmem-csi-bundle:v100.0.0 --skip-tls

More diagnostics, now with our devel branch:

Note the odd "AllCatalogSourcesHealthy: False". This pod here might be responsible for it (not sure) and reports an error:

$ kubectl logs -n olm pods/catalog-operator-84976fd7df-x5tmr

This repeats a few times but then not anymore. Deleting that pod doesn't help, the recreated one has the same problem.
