run-tests: stop matching line for missing feature

Before this change, the following unified test input would silently pass

  $ echo foo
  foo (false !)

After this change, the "foo" output is properly detected as unexpected.

The output of an handful of test had to be updated from broken conditional (that
ended up working by chance).
