Autopkgtest: Fix updating results with explicit triggers

When fetching a result with explicit triggers, always update self.results, not
just when we have a pending trigger for it. Otherwise satisfied_triggers will
be empty after reading the first result, and we clobber test results for all
triggers with the latest result.
