Fix invalid XML when UPS returns "Too Many Requests" error

[vernard]

Description (*)

During checkout (or cart page) when asking UPS for rates, there are times where I get a "Too Many Requests" error. I've replicated that API call through Postman.

When that happens, their XML response doesn't have a space in it. That includes the space in <?xml version="1.0"?>. They sent it as <?xmlversion="1.0"?> which throws an error.

Manual testing scenarios (*)

1. Do a checkout and get UPS rates.
   Sorry, this error doesn't happen in our live production. Maybe it only happens in my country (Philippines)?

I think this is something that should be reported to UPS itself too, if able?

[vernard]

I couldn't find any information about this issue on the internet. Perhaps it's not as common.

There is a Contact Form on the UPS page: https://www.ups.com/upsemail/input
but that only works if you got a UPS Account

Might report that problem there? (with link to this issue?)

i'm going to merge this MR anyway
