bolt11 invoice missing from successful outgoing payment

[danielgranhao]

We've noticed that very rarely, after paying an invoice, the payment struct returned by Breez SDK is missing the bolt11 invoice. We've checked, and the SDK gets it directly from GL.

We don't know how to reproduce this.

I expect this to be an unforeseen consequence of removing the pre-splitter, which removed the simple identification of the root payment, which therefore does not get annotated. I'll see what I can do, and where the broken assumption is :-)
