  Message : Vulkan: Fixed improperly set env variable After the first test using the Mock ICD runs, an environment variable VK_ICD_FILENAMES is set when previously it did not exists. The cleanup of that test, rather than deleting the environment variable, set it to an empty string, which the Vulkan loader would use for subsequent Vulkan tests, causing issues with Vulkan not finding the correct extensions. Had to disable two more tests since they started failing once those backends were enabled.
