EQL: integration test should create different tests for case sensitivity instead of dual running #59294
Description
Currently when a test has no case sensitivity specified, the integration test runs the test twice. This is problematic because from the framework perspective, there is only one test run.
It is not counted appropriately and also in case of failure, cannot be ran separately making diagnostics a pain.
As such, when creating the test from specs, when no case sensitivity is specified, two different specs need to be created instead of a special one.
