NexoPOS 4.8.15

This update comes with slight change over an option that wasn't correctly used. In fact, we discovered (thanks to one of you) that, we weren't able to print using the option that allows only paid orders to be printed. Fixing the issue implied having to rebuild the app, which is the reason of this release. We've also shipping NPS adapter update with this for ensuring a better compatibility.

We would like to welcome @swurzinger who've made amazing contribution to the repository. We hope to see further contributions like this in the future.

Changelog:

• fix typos and other minor translation issues
• Fixed: wrong option name used for printing paid orders
• Added: new test case for order refunded with grouped products
• Added: new language (ALBANIAN)
