lnwire: reject onion message payloads with multiple final hop fields 
BOLT 4 requires the final node to ignore an onion message whose
onionmsg_tlv contains more than one payload field, where payload fields
are the tlv types reserved for the final hop (type 64 and above). Decode
previously accumulated every such field it found, so a payload bundling
invoice_request, invoice, and invoice_error together was accepted.

Reject the payload when more than one final hop field is present. Every
entry collected in FinalHopTLVs is in the final hop range, so its count
is the number of payload fields. The round-trip test for multiple fields
becomes a rejection test, and the property test now draws at most one
payload field.
