Description:
------------
If you unset a property on a class, the __get magic method gets called (good), but it's return must match the original, now unset, property type. (bug?)

There should be a way to fully remove that property, either by reflection or unset (including the return time)

Test script:
---------------
<?php declare(strict_types=1);

class Sample {

    public int $foo = 123;      # Start as in INT
    public function __construct() {
        unset($this->foo);     # Remove the property
    }

    public function __get(string $name) {   # Gets called, since `foo` dies not exist.
        echo "__GET\n";                     # Validate that it's called
        return "string";                    # Cannot return string since foo was an int...
    }

}

$test = new Sample();
echo $test->foo; # Throws error, since __get returns a string instead of an int

Expected result:
----------------
__GET
string

Actual result:
--------------
__GET
