FocusRequester is not initialized

Steps to reproduce:

• make sure to have no .briar/ directory (i.e., no account)
• on the registration screen, enter a name
• press Enter to get to the next screen

changed milestone to %Desktop 0.2.0

added P: high Sponsor 7 T: bug labels

Clicking "OK" closes the whole app.

Same happens when pressing "Continue" on the first page. For me Briar is completely useless because I can't create an account.
