Description:
------------
On testing if an array key is available on an overloaded object
variable it doesn't check __isset before calling __get to get the
variable for checking the array key.

Reproduce code:
---------------
class MyClass
{

    public function __isset($varname)
    {
        echo 'isset' . PHP_EOL;
        return false;
    }

    public function __get($varname)
    {
        trigger_error('Key "' . $varname . '" does not exist',
E_USER_NOTICE);
    }

}

$obj = new MyClass();
var_dump( isset($obj->test[0]) );

Expected result:
----------------
isset
bool(false)

Actual result:
--------------
PHP Notice:  Key "test" does not exist in /tmp/test.php on line 14

Notice: Key "test" does not exist in /tmp/test.php on line 14
bool(false)
