refactor: Remove the registerPerson GraphQL query

- The first profile is now created after the user email validation
- NavBar is correctly updated when a user is connected but without any profile
- Always fetch identities from the server at login (no cache)
- NoIdentitiesException is thrown again
- Refactor EditIdentity to create the first profile
- Translations updated
- Tests updated

Fixes #1762
