Secret initialization from Blob storage failed

When following the steps in your README to run this project locally, I get this error messages:
```
Microsoft.Azure.WebJobs.Script.WebHost: Secret initialization from Blob storage failed due to a missing Azure Storage connection string. If you intend to use files for secrets, add an App Setting key 'AzureWebJobsSecretStorageType' with value 'Files'.
Value cannot be null.
Parameter name: provider
```

### Expected/desired behavior
app starts

### OS and Version?
Ubuntu 18.04 LTS

### Versions
- Azure Functions Core Tools (2.7.1373
- Function Runtime Version: 2.0.12507.0

Inizia con le istruzioni per la configurazione locale nel README ed esamina local.settings.json insieme ai comandi indicati di Azure Functions Core Tools. Riproduci il problema con `func extensions install`, `npm install` e `func host start`, quindi individua la configurazione necessaria per inizializzare l'host. Il lavoro è completato quando l'app si avvia localmente senza l'errore di archiviazione dei segreti.

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