f15cc7dd5b Mark private properties unused when referenced only in constructor (#1962) 
* Mark private properties unused when referenced only in constructor

If a private property is used only in constructor then most likely
it's a dead code since there is no need to have the class property.
But such static properties can be accessed between the calls.

* Ignore the private property issue on alter

* Fix the related dead code psalm

* Add a missing condition into the test
