{iothub} partitionIds are empty if user changes shared access policy registryReadWrite

### Describe the bug

The below command correctly lists _paritionIds_ until I update the shared access policy named _registryReadWrite_ to as below (enabled all 4 options)

### Errors

### Issue script & Debug output
