590a57fdec tests: Remove unused testing code (practicalswift)

Pull request description:

  Add Python dead code linter (`vulture`) to Travis.

  Rationale for allowing dead code only after explicit opt-in (via `--ignore-names`):
  * Less is more :-)
  * Unused code is by definition "untested"
  * Unused code can be an indication of bugs/logical errors. By making the contributor aware of newly introduced unused code it gives him/her an opportunity to investigate if the unused code they introduce is malignant or benign :-)
  * Unused code is hard to spot for humans and is thus often missed during manual review
  * [YAGNI](https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it)

  Based on #14312 to make linter job pass.
