Magento 2 Checkout fixes (1 Page Customwebs + More)

Are you actually using Klarna, if no then disable with bin/magento module:disable. However if you need to use it there’s a know conflict and to solve that

#46 Onestepcheckout\Iosc\Observer\Frontend\Setdefaults->callDefaults() called at [vendor/onestepcheckout/iosc/Observer/Frontend/Setdefaults.php:93]

open up and comment out the call on vendor/onestepcheckout/iosc/Observer/Frontend/Setdefaults.php:93

Then OneStepCheckout will not try to set default payment and Klarna will not request their service without all necessary data being available.
