run-tests: fixed warn detection on failures with too many output

The state "warned" was reported too often. The problem fixed here is that
warnonly was only reset when a line did not match. When there was a line too
much, warnonly remained set.
Fix this by setting more states to warnonly.

More negative testing (testing on result "Failed") has been done this time.
