Empty states.

- With the exception of the first launch states, none of the empty states should include any artwork
- First Launch Inbox State should read: Start your first Signal conversation! Tap on the + button.
- Empty Inbox State should read Done. Done. Done. Tip: add a conversation as a reminder!
- First Launch Archive State [should read][first-launch-archive] Save conversations for reference. You can swipe conversations into your Archive from the Inbox
- Empty Archive State should read Squeaky Freaking Clean. None. Zero. Zilch. Nada.
