Hreflang generator should respect http protocol

* The links that are generated should adhere to the requested http
protocol (http or https).
* We update the travis.yml to run tests on all branches.
* Update codeception to version 4.
* Change all tests to use the newly introduced BaseTestCase class.
* Fix ReverseHardLinkTest crashing test.
* Remove unused `_boostrap.php` of codeception.yml.
* Bump plugin version.
