Fix mixing named and unnamed parameters in PHP 7

[thekid]

The following code returned 1, 2, 0 instead of the correct 1, 0, 2:

uselang\Reflection;
class T {
publicstaticfunctioncreate($a, $b= 0, $c= 0) {
return [$a, $b, $c];
}
}
$t= Reflection::type(T::class)->method('create')->invoke(null, [1, 'c' => 2]);
echoimplode(', ', $t), "\n";
