jsonrpc: Allow filtering via bolt11 or payment_hash in listinvoices 

A user reported that it is sometimes cumbersome to search an invoice
based on the payment hash or the bolt11 string in the full list, which
may be required when we don't have the label available.

This adds support for querying / filtering based on the `payment_hash`
or `bolt11` string.

Changelog-Added: JSON-RPC: `listinvoices` can now query for an invoice matching a `payment_hash` or a `bolt11` string, in addition to `label`
