Sync Trigger fails when AzureWebJobsStorage is not set and functions host is running in Managed Environment (ACA)

Logic Apps Hybrid runs on ACA on the customers Kubernetes server cluster and does not have any runtime dependency on Azure Storage.
So there is no AzureWebJobsStorage setting in Hybrid Logic Apps.

in that case the SyncTrigger always fails trying to connect to blob.

Start in src/WebJobs.Script.WebHost/Management/FunctionsSyncManager.cs at lines 138-142 and trace the SyncTrigger path when AzureWebJobsStorage is absent. Reproduce the failure in an ACA Managed Environment configuration and define done as SyncTrigger completing without attempting the unavailable blob connection.
