Fix t/harness5 incorrectly failing NOTESTS runs
Fix t/harness5 incorrectly failing NOTESTS runs

When whole-file skippage is done, no tests are run and
TAP::Parser::Aggregator->all_passed actually returns false
and the t/harness5 considers the run a failed one.

Fix by using ->no_errors method instead.
