Don't remove the files in the test cases classes dtors, this was inconsistent with how they were created: we either need to create the file in the ctor and destroy it in the dtor or do both only once globally. Implement the second solution using the helper AutoRemoveFile instead of a simple static bool in GetInFileName() implementations.
