Codeception version downgrade

[Ragazzo]

We should use 1.8.* as @samdark noted, but currently that branch does not contain valid Yii2 module code. Yii2 code from master, should be pushed there. I will do PR to Codeception repo, or @qiangxue can make it too.

Currently we also have a problem with WebDriver in codeception master, and with Yii2 module cookies - cookies does not contain valid session id, they were containing it some time ago, but since it is master, something has changed and now there is no such cookie when --debug run.

Ok, i merged changes from Codeception master to 1.8.* branch. I run tests with this version, all is fine:

Since it is in branch but not in tag 1.8.2 i think we should use "codeception/codeception": "1.8.*@dev" for our application templates. Someone from core @samdark @cebe @qiangxue should handle this and travis.
