Avoid previously failed hops on PaymentFailure::AllFailedResendSafe

[tnull]

Currently, only PaymentFailure::PartialFailure carry PaymentParameters, which is why InvoicePayer retries any PaymentFailure::AllFailedResendSafes with empty previously_failed_channels:

rust-lightning/lightning-invoice/src/payment.rs

Lines 524 to 533 in 98417a1

	PaymentSendFailure::AllFailedResendSafe(_) => {
	let mut payment_cache = self.payment_cache.lock().unwrap();
	let payment_attempts = payment_cache.get_mut(&payment_hash).unwrap();
	payment_attempts.count += 1;
	if self.retry.is_retryable_now(payment_attempts) {
	core::mem::drop(payment_cache);
	Ok(self.pay_internal(params, payment_hash, send_payment)?)
	} else {
	Err(e)
	}

As this may result in a loop where a failing route is retried over and over again until we run out of time or attempts, we probably want to consider any previously failed channels in the AllFailedResendSafe case also.

As InvoicePayer is pending deprecation anyways, this probably should be fixed as part of the migration of the retry logic to ChannelManager.
