Replicate from a cluster that has backup configuration make reconciliation cycle fail

### Summary

Replicate from a cluster that has backup configuration make reconciliation cycle fail

### Current Behaviour 

The operator fail to reconcile the cluster

#### Steps to reproduce

1. Create a Cluster with backup configuration
2. Create a Cluster that replicates from the previous one

### Expected Behaviour

The operator reconcile the cluster

### Environment

- StackGres version: ?
- Kubernetes version: ?
- Cloud provider or hardware configuration: ?

### Relevant logs and/or screenshots
