Stopping Func Host Start

After running ```func host start``` for debugging and testing, I press ```CTRL+C``` to terminate the session.

After upgrading to **v3.0.3904** an error message is displayed when I press ```CTRL+C```...
```

Reporting this as I'm not sure if there is an error or not

Reproduce `func host start` on version 3.0.3904, stop it with CTRL+C, and compare the gRPC EventStream and Kestrel messages shown in the report. Trace the shutdown handling around the EventStream and determine whether the aborted request is expected; done means establishing the expected behavior and identifying a focused correction if it is not.
