Remove main PaymentExpress class

Overview

Removes no-longer-working Payment Express processor class

Before

Now you see it

After

Now you don't

Technical Details

I recently identified that this processor had been broken for a long time & removed the broken IPN class - 7b3e290

At that time I didn't remove the main class as I was unsure how to deal with any legacy transactions related to it.

However, @mattwire pointed out he had done work earlier to make CiviCRM cope with not-present processor classes and,
on testing, I was unable to trigger any errors after setting up a contribution page & an event page & making a payment
and then deleting the class. I couldn't edit the contribution, but with appropriate in app messaging and no fatal
error.

Is there any metadata or SQL files that need updating now this doesn't exist? Or did we already do that?

@mattwire already done -I did a grep for PaymentExpress.

Looks like your earlier work paid off & made this easier than I expected

Cool!
