Crash when returning to app after closing during email verification

[ouchadam]

Steps to reproduce

1. Start the account creation process
2. When asked to confirm the email, force close the app
3. Relaunch the app and notice the email verification screen has opened
4. Continue the account creation process by clicking the link in the email
5. Notice the app crashes

Outcome

What did you expect?

If the app has been force stopped or crashes during account creation we should reset the flow back to the beginning as it means we've lost track of all the onboarding previous steps. The app is able to correctly restore the registration when the system uses its restoration mechanism (task switching)

What happened instead?

The app shortcuts to the email verification screen without the data from the previous steps, causing the continuation of the account creation to crash due to missing information
