Test running ravend with -reindex and -reindex-chainstate options.

- Start a single node and generate 3 blocks.
- Stop the node and restart it with -reindex. Verify that the node has re-indexed up to block 3.
- Stop the node and restart it with -reindex-chainstate. Verify that the node has re-indexed up to block 3.
