Issue/1841 enable WebID-TLS tests

[SarthakDudhe]

Summary

• re-enable the skipped WebID-TLS integration tests
• add CI host aliases for tim.localhost and nicola.localhost
• restore the intended TLS test coverage path now that hostname resolution is handled

Fixes#1841.
Tests

• npm run lint
• local TLS suite still requires host resolution for tim.localhost / nicola.localhost
