wallet.use_change is a weird preference using which a user can disable
sending new change to change addresses.
However the setting can be toggled at ~any time; and the user might
have pre-existing balance on change addresses, which we should not hide.
Previously if a local tx got broadcast, it was still displayed as local
in the history until it got mined (or some other action forced a full refresh).
The app hangs indefinitely if we try to quit it while one of
these threads is active, because once asyncio has shut down,
futures never return. This was already fixed for lightning
payments in c5dc133, but there are many other cases.
- they are now distinguished from local by the status text "in %d blocks"
- this status text needs updating occasionally: on new blocks,
and some lnwatcher interactions, hence new event: "adb_set_future_tx"

QEInvoice/QEInvoiceParser now properly split for mapping to Invoice type (QEInvoice)
and parsing/resolving of payment identifiers (QEInvoiceParser).
additionally, old, unused QEUserEnteredPayment was removed.
invoices are now never saved with user-entered amount if the original invoice
did not specify an amount (e.g. address-only, no-amount bip21 uri, or no-amount
lightning invoice). Furthermore, QEInvoice now adds an isSaved property so the
UI doesn't need to infer that from the existence of the invoice key.
Payments of lightning invoices are now triggered through QEInvoice.pay_lightning_invoice(),
using the internally kept Invoice instance. This replaces the old call path of
QEWallet.pay_lightning_invoice(invoice_key) which required the invoice to be saved
in the backend wallet before payment.
The LNURLpay flow arriving on InvoiceDialog implicitly triggered payment, this is
now indicated by InvoiceDialog.payImmediately property instead of inferrred from the
QEInvoiceParser isLnurlPay property.
