"Invalid document handle is set" when calling for document

Hi,
I stumbled on an issue with your fork for php7 support. The library is compiling fine and working when creating a simple pdf with text or one image or so. But if try to add more pages to a document I get the Invalid document handle is set -error. This happens after third page is added.

I've tried to debug the issue but my C/Zend skills are very limited.
It appears that the php_harudoc_dtor is called too early when it should be called at the end of my script (I think, at least that's how it worked on the latest pecl-haru 1.0.4 on php 5).

Here's an example of my test script.

<?php

$doc = new HaruDoc();

for($i = 1; $i <= 10; $i++) {
    echo "Calling doc->addPage() ".$i."\n";
    $p = $doc->addPage();
    echo "\n";
}

$doc->save("test.pdf"); 

I get a HaruException "An invalid document handle is set" on 4th loop
I'm running php 7.2 on apache

I tried the libharu C-library straight on and it worked as expected.
