Registering keeps failing on password confirmation step

[byCedric]

Description

When registering a new account, I used $ EXPO_STAGING=1 expo ..., the password confirmation prompt always fails. It's related to us fetching previous answers, but that doesn't seem to be provided.

Expected Behavior

Succeeds when I confirm the password successfully.

Observed Behavior

(node:22935) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'password' of undefined

Reproducible Demo

• Try to register

Looks like a limitation from prompts, maybe we should add a custom element for password confirmation?

An issue for this functionality was created, but there is no PR yet.
