182: compilation fix: PlatformTestCase.myFilesToDelete made non-static in Platform

some code from `PlatformTestCase` were copy-pasted to `KotlinLightCodeInsightFixtureTestCaseBase` because `PlatformTestCase` is not in it's type hierarchy, and thus we cant use these methods from `PlatformTestCase` when they became non-static
