Description

When the sign-up transfer after an OAuth sign-in fails, for example on a 429 or a network error, the SSO callback returns the user to the sign-in start screen. The sign-in is still transferable with the external_account_not_found code, so the start screen showed "The External Account was not found." to a new user.

SignInStart now shows that message only when transferable is false. Otherwise it shows the generic error.
