This tests the case where the same UTXO is spent twice on two separate
blocks as part of a reorg.
ab0
/ \
aa1 [tx1] bb1 [tx2]
| |
aa2 bb2
| |
aa3 bb3
|
bb4
Problematic case:
1. User 1 receives XEP in tx1 from utxo1 in block aa1.
2. User 2 receives XEP in tx2 from utxo1 (same) in block bb1
3. User 1 sees 2 confirmations at block aa3.
4. Reorg into bb chain.
5. User 1 asks `listsinceblock aa3` and does not see that tx1 is now
invalidated.
Currently the solution to this is to detect that a reorg'd block is
asked for in listsinceblock, and to iterate back over existing blocks up
until the fork point, and to include all transactions that relate to the
node wallet.
