`node index.js`, register new aliases and send non alias txs to alias registration address, see that unprocessed txs are picked up when the next block is found and logged
Review new unit tests and `npm test`
Change `config.txHistoryPageSize` to some value > 11 and `npm test` again. Tests still pass.
(Note that 2 unit tests are hardcoded to not require additional pages of data based on available mocks data of 11 unconfirmed and then confirmed txs).
