lnpeer.pay: also log hops_data for trampoline_onion

Browse Source 
We were already logging the outer-layer hops_data,
now we also log the inner trampoline-onion hops_data.

Example:
```
  1.12 | I | P/lnpeer.Peer.[MockLNWallet, alice->bob] | lnpeer.pay len(route)=1
  1.12 | I | P/lnpeer.Peer.[MockLNWallet, alice->bob] |   0: edge=9926297x9781928x61754 hop_data=<OnionHopsDataSingle. payload={'amt_to_forward': {'amt_to_forward': 100000000}, 'outgoing_cltv_value': {'outgoing_cltv_value': 601299}, 'payment_data': {'payment_secret': b'\xd2\x9cl\xdfV\xd4\xea_\x06{\xed\xc9\xc7\xa6\xf5\xc0\n\x1a\x95\xad\xad\xd2F\xb8;&\x9f\xa1\xe1\xd1\x07H', 'total_msat': 100000000, 'amount_msat': 100000000}}. hmac=None>
