[HLE] Fix StoreData layout and implement IDatabaseService.Append (#43)

Browse Source 
- Fixes `StoreData` layout/update handling so `UpdateLatest` returns the stored Mii data correctly.
- Implements `IDatabaseService.Append` (https://switchbrew.org/wiki/Shared_Database_services#IDatabaseService)

Also adds regression tests for `UpdateLatest` and `Append`.

(Might) fix Mario Kart 8 Deluxe crashing on first boot due to failed Mii verification check (due to custom Mii from emulator), and potentially Tomodachi Life: Living the Dream for the "Import Mii from system" option.
