($x ?? $y) is defined as being equivalent to (isset($x) ? $x : $y) so __isset() should be getting
called.

Description:
------------
The issue appears when using the new null coalescing operator on object parameters, when the defined
class has override the magic __get() and an error is triggered inside it.
The script runs the __get() method and not the __isset(), so the error on __get() is triggered when
the operator is used.
Test script:

Expected result:
----------------
The expexted result should be not to trigger the error within the __get() method
GET
string(6) "value1"
GET
string(7) "default"
Actual result:
--------------
The error is triggered
GET
string(6) "value1"
GET
