"""Test HD Wallet keypool restore function.
Two nodes. Node1 is under test. Node0 is providing transactions and generating blocks.
- Start node1, shutdown and backup wallet.
- Generate 110 keys (enough to drain the keypool). Store key 90 (in the initial keypool) and key 110 (beyond the initial keypool). Send funds to key 90 and key 110.
- Stop node1, clear the datadir, move wallet file back into the datadir and restart node1.
- connect node1 to node0. Verify that they sync and node1 receives its funds."""
