Add SSL, redirects, SEO plugin tests and fix fake test issues

- Add real integration tests for SSL, redirects, and SEO plugins
  using Chrome session helpers for live URL testing
- Remove fake "format" tests that just created dicts and asserted on them
  (apt, pip, npm provider output format tests)
- Remove npm integration test that created dirs then checked they existed
- Fix SQLite search test to use SQLITEFTS_DB constant instead of hardcoded value
