ttests: test payreq status after getting paid via LN
The test failures corresponding to single-part (non-MPP) payments expose a bug.
see https://github.com/spesmilo/electrum/blob/196b4c00a35b288f28885c0ceb8afdd5ffbd9a0f/electrum/lnpeer.py#L1538-L1539
`lnworker.add_received_htlc` is not called for single-part payments...
