[A clear and concise description of what the bug is.]

AzureMachineTemplate controller sometimes fails with:

E0224 22:27:33.232967       1 controller.go:317] controller/azuremachinetemplate "msg"="Reconciler error" "error"="failed to create scope: failed to retrieve AzureClusterIdentity external object \"capz-e2e-wdy4nd\"/\"cluster-identity\": AzureClusterIdentity.infrastructure.cluster.x-k8s.io \"cluster-identity\" not found (from https://storage.googleapis.com/kubernetes-jenkins/pr-logs/pull/kubernetes-sigs_cluster-api-provider-azure/2119/pull-cluster-api-provider-azure-e2e-v1beta1/1496972953802248192/artifacts/clusters/bootstrap/controllers/capz-controller-manager/capz-controller-manager-5bc6f7f446-kgpkr/manager.log) 

Eventually, the error seems to go away but this happens multiple times on each cluster create. We should investigate why the object is not found: is it actually being temporarily removed or is it not able to find it even if it's there? What can we do to prevent this error?
