Eng 1427 fix database integration tests

[saurav-c]

Describe your changes and why you are making these changes

This PR fixes our database integration tests. One of the operator test cases was failing because we did not update the ID of the expected operator.

It also splits up the make test-database into a couple rules, so that devs can test against specific database types. More documentation for testing can be found here.
