Prestashop: Error upgrading to 1.7.6 with php 5.6

[davidglezz]

Upgrading from 1.6.0 to 1.7.6 (php 5.6):
PHP Fatal error: Call to a member function get() on null in /var/www/html/install/upgrade/php/ps_1760_copy_data_from_currency_to_currency_lang.php on line 55

Sorry, I did not have time to try it in a fresh prestashop.
I was able to update up to 1.7.5.2, but not up to 1.7.6.

Steps to reproduce the behavior:

1. From old PrestaShop version (1.6.0.x by example), with php 5.6
2. Do manual upgrade https://devdocs.prestashop.com/1.7/basics/keeping-up-to-date/upgrade/#manual-upgrade-process-details
3. See error above

Additional information
PrestaShop version: 1.7.6
PHP version: 5.6
MySQL : 5.5

I removed the Autoupgrade label as the module is not concerned by this issue. We talk about a manual upgrade.

As we reproduce the issue, we could find easily find the root cause. Here is a fix for that: https://github.com/PrestaShop/PrestaShop/pull/14620

I've tested this fix trying to update 1.7.2.4 to 1.7.6

Downloaded the latest ZIP
updated the upgrade.php according to 14620
ran the 1-step upgrade using local directory as source option

same exact error.

I'm using PHP 5.6
