Bump self-tests to 4.2 requirements (PHP 8.0 and PostgreSQL 13)

Note we also have applied a couple of extra changes:

- Rename the both travis and gha job names to match.
- Refactor travis noticeably to better separarte validate
  and integration tests, avoiding the "phantom" job that
  was caused by the matrix behaviour.
