* Fix return type in model setters.
Previously return type was same, as method arguments. It`s wrong, and cause errors like
"Return value of Foo::setSuccess() must be of the type bool, object returned"
We cant use self and current {{classname}} as return type, because that can break class inheritance. So, better remove type hint on setters, until PHP-devs dont make realization for return static
* Add return self type hint for setters
* Revert "Add return self type hint for setters"
