E6 fixup: use trim() + empty-string guard in setService(); use newEngine() in tests

- str_replace('/', '', \$index) → trim(\$index, '/') to preserve internal
  slashes in multi-segment index paths (e.g. 'phabricator/prod' must
  stay intact; only leading/trailing slashes are stripped).
- Add empty-string guard: after trim, throw a clear exception if the
  result is '' so misconfigured paths fail loudly at setService() rather
  than silently at query time with a confusing endpoint URL.
- Replace direct new VyOSElasticModernFulltextStorageEngine() in the
  four new test methods with \$this->newEngine() to avoid PHP fatal on
  abstract class instantiation.
