ignore_status is False by default, so no need to do explicitly pass it
to the function. Also, as we are putting something that can throw an
exception, you can wrap it in a try/except module that throws a
error.TestError exception in case our module removal still fails.
Other than that, I agree with Avi that we should avoid adding commented
lines, and prefer python constructs over shell ones.
