The Chrome suite now drives the private key export screen as it drives the
recovery phrase screen: the correct password shows the key, leaving by the
settings gear empties the screen, and leaving while the password is still
being checked never puts the key on it. The cases use the imported key
wallet: leaving drops the address the screen was showing, so on an HD
wallet a late decrypt fails by itself and the liveness check would go
untested. Only the phrase screen's state reader now takes the screen's
name, and serves both; the wipe assertion takes the secret, as before. A
second open in one popup session throws (#460), so the cases reopen the
popup before it.
