A fresh login creates a new key backup

[BillCarsonFr]

Step to reproduce:

• Do a new login
• Verify with the passphrase

If you don't have other sessions at the time of this fresh login, you history will be lost

Looks like that clicking on Restore From backup in settings will reset everytime (after asking for the 4s passphrase)
