Problem description

Prepare database with always encrypted feature. Update connection details in ExecuteBatchTest.java and run tests in attached gradle project.

Expected behaviour: No column is encrypted, so it does not matter, whether columnEncryptionSetting is enabled or not.
Actual behaviour: Only test with connection string containing “columnEncryptionSetting=Enabled” fails.
