CR.status.conditions and CR.status.LastSyncTimestamp are not updated in some code branches

1. CR.status.LastSyncTimestamp should also be updated in the "else" code branch: 
https://github.com/openshift/cloud-credential-operator/blob/4cb9faca62c31ebea9a11b55f7af764be4ee2cd8/pkg/operator/credentialsrequest/credentialsrequest_controller.go#L1054

2. r.Client.Status().Update is not called on the CR object in memory after this line:
https://github.com/openshift/cloud-credential-operator/blob/4cb9faca62c31ebea9a11b55f7af764be4ee2cd8/pkg/operator/credentialsrequest/credentialsrequest_controller.go#L713
So CR.status.conditions are not updated. 

This results from a static code check.
