Subject: [PATCH] Allow building Invoice from Bolt11InvoiceDescriptionRef

Small annoyance I found when updating in one of my downstream projects.
Now that there are 2 types of Bolt11InvoiceDescription you can't just
copy one from one invoice to a new one. This makes it so we can again
build an invoice from the ref version.
