Integration test script should test REST API

Integration test script should test REST API

**Describe the solution you'd like**
After running queries, use the REST API to get a list of queries and see if they are there. We can use curl for this.

**Describe alternatives you've considered**
None

**Additional context**
None

Locate the existing integration test script and the REST API entry point, then run the current integration tests to understand their query flow. Extend the script to request the query list through the REST API after queries run and verify those queries are present; the integration tests should pass.
