Make sure test server processes are killed before the temporary directories are removed. Let Modified_Testcase handle the top-level temporary directory. Don't let Modified_testcase handle any subdirectories because: * teardown will try to remove them in the wrong order * removing the top level is enough Fixes #1344 Signed-off-by: Jussi Kukkonen <jkukkonen@vmware.com>
