BUG: Assert-AzureServicePrincipalForRbac when saving credentials to Key Vault

[JamesDawson]

Due to the line below, when saving updated service principal credentials to Key Vault the appId field is null - rendering the stored credential details useless - it works fine when updating app registration credentials.

Corvus.Deployment/module/functions/azure/aad/Assert-AzureServicePrincipalForRbac.ps1

Line 204 in df126c4

appId = $Application.appId
