Grpc: listpays & listsendpays returns empty description

[michaelWuensch]

Issue and Steps to Reproduce

I used CoreLightning 24.08 to create an invoice with a description.
When I pay this invoice using CoreLightning 24.11 and then fetch all payments with grpc using listpays & listsendpays, the optional description field of the returned response for the payment is empty and HasDescription is false.
The bolt11 field contains the bolt11 which also includes the description, but it has to be extracted manually which is not good.
