Jakob Unterwurzacher a80d798c2d tests: reverse: don't run tests that ignore "-plaintextnames" twice
TestMain() runs all tests twice, once with plaintextnames=true and once
with false. Several tests mount their own filesystem and ignore the
plaintextnames variable. It makes no sense to run them twice, so
skip execution when plaintextnames is set.
