Cannot open order in backend without a shipping method

Cannot open order in backend without a shipping method.
This happens e.g when only virtual products are purchased (downloads, gift cards, ...)

Magento2/Block/Adminhtml/Order/View/Tab/Intelipost.php

Line 138 in 8159946

if (strpos($this->getOrder()->getShippingMethod(), 'intelipost') !== false) {

Changing that line to this one would fix it:
if (strpos($this->getOrder()->getShippingMethod() ?? '', 'intelipost') !== false) {

Hi Stephan.
Thanks for the feedback we'll fix it and update it as soon as possible.

Thank you @contardi
We just realized, that placing the order already creates issues: #20
But it will be a similar fix that can be done all at once =)
