feat(travis): push notifications to saltstack-formulas.zulipchat.com

* Use `%2F` for the forward slash in the topic name:
  - https://docs.travis-ci.com/user/triggering-builds/
  - https://www.degraeve.com/reference/urlencoding.php
* Use Travis `if` conditional rather than `secret` encrypted enviroment
  variable workaround suggested:
  - Not a secret, just the bot's API key
  - Need to be able to modify parts of the URL in certain situations,
    such as the weekly `master` branch tests
