[This function](https://github.com/Azure/azure-functions-powershell-worker/blob/master/src/Azure.Functions.PowerShell.Worker/PowerShell/Host/HostUserInterface.cs#L156-L159) never gets fired when you do a `Write-Error` so either we've got a bug in the PowerShell SDK or I've set up the host incorrectly. Verbose, Warning, and regular logs work fine.
