harness: cleanup tests to not override is_finished() where possible

If is_finished() cannot be converted into get_finish_string(), i.e.
is_finished() is a condition that depends on multiple output lines make sure
we call super().is_finished(line) on every line so that we catch Assertion
errors etc. that are checked for in TestCommon.is_finished().
