Adaption to splitted ProcessOrderCreateEvent

[Poepp]

Hi!

Is it planned to update/adapt cart_paypal to the splitted ProcessOrderCreateEvent in cart base extension?

Edit from my side:
I finally realized that the vast majority of the work was already done by Daniel and it was just a bug that needs to be fixed. I think I was able to fix this with the pull request below.

Thanks

I have tested this pull request with TYPO3 v10.4.26 and Cart 8.2.3.
Works like a charm. Thanks for the coding work.

@extcode Is it possible to merge and release this.
