Request URL is invalid when trying to run a command against scale set VMs

The JAR is shaded here, but I'm getting the following stacktrace when trying to run a command against scale set VMs.

```

```

When looking at the activity log in Azure, the authorization scope ID (scrubbed) is listed as:

```
"id": "/subscriptions//resourceGroups//providers/Microsoft.Compute/virtualMachineScaleSets//virtualmachines/subscriptions//resourceGroups//providers/Microsoft.Compute/virtualMachineScaleSets//virtualMachines//runCommand",
```

Which seems to repeat the subscriptions through virtual machine text twice, though the second time using an all-caps version of the resource group name.

Inizia con i frame di AzureClient.java nello stack trace e confrontali con l'ID dell'ambito di autorizzazione del Azure activity-log mostrato nel report. Traccia la costruzione della richiesta scale-set VM runCommand e verifica il completamento riproducendo una richiesta il cui ambito di autorizzazione contenga ogni percorso della risorsa una sola volta.

Scritto dal modello di indicizzazione a partire dal testo della issue.
