refactor: Fix phpstan method.impossibleType

[neznaika0]

Description
I have updated the tests so that they change the object. It's so easy to track event triggers instead of bool checks.

Fixed the message at the same time: Call to an undefined method Events::unInitialize()

It's not that easy to rebase branches

You can refer to here if you are switching the base branch. The git rebase --onto is a life-saver.

Thanks, I'll try. Before that, I used cherry-pick and reset --hard

@neznaika0 I wrote a blog post about rebase as well FYI https://samsonasik.wordpress.com/2015/09/16/practical-git-4-rebasing-conflicted-task-branch-against-primary-branch/
