run-tests: produce error on running a failing test

This patch fixes a regression recently introduced by a refactoring (see
92a6b16c9186 and about 200 previous changesets from Gregory Szorc).  It produce
an error message everytime with a test filename which gets fail while testing
except at one condition when '--nodiff' option is enabled.
