Follow up to #496

In #496 we made some adjustments that should be treating "Authorization" the same as "Sale" and set the Order to Processing so that inventory updates accordingly.

We have a user that's been waiting on this particular feature, but now they've updated to 1.2.4 and I have confirmed they have Authorization payment type set, but it's still leaving the orders in Pending status and not updating inventory.

Hi yes it is set to authorization. Authorizations are going through but again order is going to hold still instead of processing and inventory is not being reduced. This only impacts PayPal Express and started after the update before last. I also use Pay Flow and it still works flawlessly. Just Express has the issue.

This may be related to #553 but I'm not sure.

I think the same guy from our ticket has now reached out to another plugin developer, who has now circled back to us asking for this same fix: https://mail.google.com/mail/u/0/#inbox/1588b5caa406ee0a
