Deposit claim fees are not reflected

[JssDWt]

• When calling receive_payment to get a static deposit address, receive_payment returns a fee of 0.
• When calling list_payments, the deposit payment has fees: 0, even though fees were paid to claim the utxo.

The 2nd point is a duplication of #331. The 1st is a separate issue, so I propose we make this issue just about that.

Actually this issue is different, because the fee is 0 forever. In #331 the fees fix themselves after some time.

@JssDWt please detail exactly what is needed from Spark and add a link to any relevant slack discussions in the tracker. If there's no thread let's open one, and if there's an existing thread, ping them there for status and link to the tracker.

This is waiting for an added field to the SSP deposit_amount when querying transfers, that contains the original onchain amount. Once we have that , we can easily deduce the used fees. It is due to be deployed this week.
