azure-pipelines-tasks: Inline SQL Script doesn't work on 2017 Hosted Agent

We’re using the Azure SQL Database Deployment task’s “Inline SQL Script” in a few build definitions.

https://github.com/Microsoft/vsts-tasks/blob/master/Tasks/SqlAzureDacpacDeployment/README.md

This worked on the “Hosted” queue, but fails on the “Hosted 2017” queue:
